+# Development, Testing and Contributing
+
+  1. Make sure you have a running Docker daemon
+     (Install for [MacOS](https://docs.docker.com/docker-for-mac/))
+  1. Use a version of Go that supports [modules](https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more) (e.g. Go 1.11+)
+  1. Fork this repo and `git clone` somewhere to `$GOPATH/src/github.com/golang-migrate/migrate`
+      * Ensure that [Go modules are enabled](https://golang.org/cmd/go/#hdr-Preliminary_module_support) (e.g. your repo path or the `GO111MODULE` environment variable are set correctly)
+  1. Install [golangci-lint](https://github.com/golangci/golangci-lint#install)
+  1. Run the linter: `golangci-lint run`
+  1. Confirm tests are working: `make test-short`
+  1. Write awesome code ...
+  1. `make test` to run all tests against all database versions
+  1. Push code and open Pull Request
+ 
+Some more helpful commands:
+
+  * You can specify which database/ source tests to run:
+    `make test-short SOURCE='file go_bindata' DATABASE='postgres cassandra'`
+  * After `make test`, run `make html-coverage` which opens a shiny test coverage overview.
+  * `make build-cli` builds the CLI in directory `cli/build/`.
+  * `make list-external-deps` lists all external dependencies for each package
+  * `make docs && make open-docs` opens godoc in your browser, `make kill-docs` kills the godoc server.
+    Repeatedly call `make docs` to refresh the server.
+  * Set the `DOCKER_API_VERSION` environment variable to the latest supported version if you get errors regarding the docker client API version being too new.

+# FAQ
+
+#### How is the code base structured?
+  ```
+  /          package migrate (the heart of everything)
+  /cli       the CLI wrapper
+  /database  database driver and sub directories have the actual driver implementations
+  /source    source driver and sub directories have the actual driver implementations
+  ```
+
+#### Why is there no `source/driver.go:Last()`?
+  It's not needed. And unless the source has a "native" way to read a directory in reversed order,
+  it might be expensive to do a full directory scan in order to get the last element.
+
+#### What is a NilMigration? NilVersion?
+  NilMigration defines a migration without a body. NilVersion is defined as const -1.
+
+#### What is the difference between uint(version) and int(targetVersion)?
+  version refers to an existing migration version coming from a source and therefore can never be negative.
+  targetVersion can either be a version OR represent a NilVersion, which equals -1.
+
+#### What's the difference between Next/Previous and Up/Down?
+  ```
+  1_first_migration.up.extension           next ->  2_second_migration.up.extension      ...
+  1_first_migration.down.extension  <- previous     2_second_migration.down.extension    ...
+  ```
+
+#### Why two separate files (up and down) for a migration?
+  It makes all of our lives easier. No new markup/syntax to learn for users
+  and existing database utility tools continue to work as expected.
+
+#### How many migrations can migrate handle?
+  Whatever the maximum positive signed integer value is for your platform.
+  For 32bit it would be 2,147,483,647 migrations. Migrate only keeps references to
+  the currently run and pre-fetched migrations in memory. Please note that some
+  source drivers need to do build a full "directory" tree first, which puts some
+  heat on the memory consumption.
+
+#### Are the table tests in migrate_test.go bloated?
+  Yes and no. There are duplicate test cases for sure but they don't hurt here. In fact
+  the tests are very visual now and might help new users understand expected behaviors quickly.
+  Migrate from version x to y and y is the last migration? Just check out the test for
+  that particular case and know what's going on instantly.
+
+#### What is Docker being used for?
+  Only for testing. See [testing/docker.go](testing/docker.go)
+
+#### Why not just use docker-compose?
+  It doesn't give us enough runtime control for testing. We want to be able to bring up containers fast
+  and whenever we want, not just once at the beginning of all tests.
+
+#### Can I maintain my driver in my own repository?
+  Yes, technically thats possible. We want to encourage you to contribute your driver to this repository though.
+  The driver's functionality is dictated by migrate's interfaces. That means there should really
+  just be one driver for a database/ source. We want to prevent a future where several drivers doing the exact same thing,
+  just implemented a bit differently, co-exist somewhere on GitHub. If users have to do research first to find the
+  "best" available driver for a database in order to get started, we would have failed as an open source community.
+
+#### Can I mix multiple sources during a batch of migrations?
+  No.
+
+#### What does "dirty" database mean?
+  Before a migration runs, each database sets a dirty flag. Execution stops if a migration fails and the dirty state persists,
+  which prevents attempts to run more migrations on top of a failed migration. You need to manually fix the error
+  and then "force" the expected version.
+
+#### What happens if two programs try and update the database at the same time?
+  Database-specific locking features are used by *some* database drivers to prevent multiple instances of migrate from running migrations on
+  the same database at the same time. For example, the MySQL driver uses the `GET_LOCK` function, while the Postgres driver uses
+  the `pg_advisory_lock` function.
+
+#### Do I need to create a table for tracking migration version used?
+No, it is done automatically.
+
+#### Can I use migrate with a non-Go project?
+Yes, you can use the migrate CLI in a non-Go project, but there are probably other libraries/frameworks available that offer better test and deploy integrations in that language/framework.
+
+#### I have got an error `Dirty database version 1. Fix and force version`. What should I do?
+Keep calm and refer to [the getting started docs](GETTING_STARTED.md#forcing-your-database-version).

+# Getting started
+Before you start, you should understand the concept of forward/up and reverse/down database migrations.
+
+Configure a database for your application. Make sure that your database driver is supported [here](README.md#databases).
+
+## Create migrations
+Create some migrations using migrate CLI. Here is an example:
+```
+migrate create -ext sql -dir db/migrations -seq create_users_table
+```
+Once you create your files, you should fill them.
+
+**IMPORTANT:** In a project developed by more than one person there is a chance of migrations inconsistency - e.g. two developers can create conflicting migrations, and the developer that created their migration later gets it merged to the repository first.
+Developers and Teams should keep an eye on such cases (especially during code review).
+[Here](https://github.com/golang-migrate/migrate/issues/179#issuecomment-475821264) is the issue summary if you would like to read more.
+
+Consider making your migrations idempotent - we can run the same sql code twice in a row with the same result. This makes our migrations more robust. On the other hand, it causes slightly less control over database schema - e.g. let's say you forgot to drop the table in down migration. You run down migration - the table is still there. When you run up migration again - `CREATE TABLE` would return an error, helping you find an issue in down migration, while `CREATE TABLE IF NOT EXISTS` would not. Use those conditions wisely.
+
+In case you would like to run several commands/queries in one migration, you should wrap them in a transaction (if your database supports it).
+This way if one of commands fails, our database will remain unchanged.
+
+## Run migrations
+Run your migrations through the CLI or your app and check if they applied expected changes.
+Just to give you an idea:
+```
+migrate -database YOUR_DATABASE_URL -path PATH_TO_YOUR_MIGRATIONS up
+```
+
+Just add the code to your app and you're ready to go!
+
+Before committing your migrations you should run your migrations up, down, and then up again to see if migrations are working properly both ways.
+(e.g. if you created a table in a migration but reverse migration did not delete it, you will encounter an error when running the forward migration again)
+It's also worth checking your migrations in a separate, containerized environment. You can find some tools at the [end of this document](#further-reading).
+
+**IMPORTANT:** If you would like to run multiple instances of your app on different machines be sure to use a database that supports locking when running migrations. Otherwise you may encounter issues.
+
+## Forcing your database version
+In case you run a migration that contained an error, migrate will not let you run other migrations on the same database. You will see an error like `Dirty database version 1. Fix and force version`, even when you fix the erred migration. This means your database was marked as 'dirty'.
+You need to investigate the migration error - was your migration applied partially, or was it not applied at all? Once you know, you should force your database to a version reflecting it's real state. You can do so with `force` command:
+```
+migrate -path PATH_TO_YOUR_MIGRATIONS -database YOUR_DATABASE_URL force VERSION
+```
+Once you force the version and your migration was fixed, your database is 'clean' again and you can proceed with your migrations.
+
+For details and example of usage see [this comment](https://github.com/golang-migrate/migrate/issues/282#issuecomment-530743258).

+# Migrations
+
+## Migration Filename Format
+
+A single logical migration is represented as two separate migration files, one
+to migrate "up" to the specified version from the previous version, and a second
+to migrate back "down" to the previous version.  These migrations can be provided
+by any one of the supported [migration sources](./README.md#migration-sources).
+
+The ordering and direction of the migration files is determined by the filenames
+used for them.  `migrate` expects the filenames of migrations to have the format:
+
+    {version}_{title}.up.{extension}
+    {version}_{title}.down.{extension}
+
+The `title` of each migration is unused, and is only for readability.  Similarly,
+the `extension` of the migration files is not checked by the library, and should
+be an appropriate format for the database in use (`.sql` for SQL variants, for
+instance).
+
+Versions of migrations may be represented as any 64 bit unsigned integer.
+All migrations are applied upward in order of increasing version number, and
+downward by decreasing version number.
+
+Common versioning schemes include incrementing integers:
+
+    1_initialize_schema.down.sql
+    1_initialize_schema.up.sql
+    2_add_table.down.sql
+    2_add_table.up.sql
+    ...
+
+Or timestamps at an appropriate resolution:
+
+    1500360784_initialize_schema.down.sql
+    1500360784_initialize_schema.up.sql
+    1500445949_add_table.down.sql
+    1500445949_add_table.up.sql
+    ...
+
+But any scheme resulting in distinct, incrementing integers as versions is valid.
+
+It is suggested that the version number of corresponding `up` and `down` migration
+files be equivalent for clarity, but they are allowed to differ so long as the
+relative ordering of the migrations is preserved.
+
+The migration files are permitted to be "empty", in the event that a migration
+is a no-op or is irreversible. It is recommended to still include both migration
+files by making the whole migration file consist of a comment.
+If your database does not support comments, then deleting the migration file will also work.
+Note, an actual empty file (e.g. a 0 byte file) may cause issues with your database since migrate
+will attempt to run an empty query. In this case, deleting the migration file will also work.
+For the rational of this behavior see:
+[#244 (comment)](https://github.com/golang-migrate/migrate/issues/244#issuecomment-510758270)
+
+## Migration Content Format
+
+The format of the migration files themselves varies between database systems.
+Different databases have different semantics around schema changes and when and
+how they are allowed to occur
+(for instance, [if schema changes can occur within a transaction](https://wiki.postgresql.org/wiki/Transactional_DDL_in_PostgreSQL:_A_Competitive_Analysis)).
+
+As such, the `migrate` library has little to no checking around the format of
+migration sources.  The migration files are generally processed directly by the
+drivers as raw operations.
+
+## Reversibility of Migrations
+
+Best practice for writing schema migration is that all migrations should be
+reversible.  It should in theory be possible for run migrations down and back up
+through any and all versions with the state being fully cleaned and recreated
+by doing so.
+
+By adhering to this recommended practice, development and deployment of new code
+is cleaner and easier (cleaning database state for a new feature should be as
+easy as migrating down to a prior version, and back up to the latest).
+
+As opposed to some other migration libraries, `migrate` represents up and down
+migrations as separate files.  This prevents any non-standard file syntax from
+being introduced which may result in unintended behavior or errors, depending
+on what database is processing the file.
+
+While it is technically possible for an up or down migration to exist on its own
+without an equivalently versioned counterpart, it is strongly recommended to
+always include a down migration which cleans up the state of the corresponding
+up migration.

+# migrate
+
+__Database migrations written in Go. Use as [CLI](#cli-usage) or import as [library](#use-in-your-go-project).__
+
+* Migrate reads migrations from [sources](#migration-sources)
+   and applies them in correct order to a [database](#databases).
+* Drivers are "dumb", migrate glues everything together and makes sure the logic is bulletproof.
+   (Keeps the drivers lightweight, too.)
+* Database drivers don't assume things or try to correct user input. When in doubt, fail.
+
+Forked from [mattes/migrate](https://github.com/mattes/migrate)
+
+## Databases
+
+Database drivers run migrations. [Add a new database?](database/driver.go)
+
+* [PostgreSQL](database/postgres)
+* [PGX v4](database/pgx)
+* [PGX v5](database/pgx/v5)
+* [Redshift](database/redshift)
+* [Ql](database/ql)
+* [Cassandra / ScyllaDB](database/cassandra)
+* [SQLite](database/sqlite)
+* [SQLite3](database/sqlite3) ([todo #165](https://github.com/mattes/migrate/issues/165))
+* [SQLCipher](database/sqlcipher)
+* [MySQL / MariaDB](database/mysql)
+* [Neo4j](database/neo4j)
+* [MongoDB](database/mongodb)
+* [CrateDB](database/crate) ([todo #170](https://github.com/mattes/migrate/issues/170))
+* [Shell](database/shell) ([todo #171](https://github.com/mattes/migrate/issues/171))
+* [Google Cloud Spanner](database/spanner)

+* [ClickHouse](database/clickhouse)
+* [Firebird](database/firebird)
+* [MS SQL Server](database/sqlserver)
+* [rqlite](database/rqlite)
+
+### Database URLs
+
+Database connection strings are specified via URLs. The URL format is driver dependent but generally has the form: `dbdriver://username:password@host:port/dbname?param1=true&param2=false`
+
+Any [reserved URL characters](https://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_reserved_characters) need to be escaped. Note, the `%` character also [needs to be escaped](https://en.wikipedia.org/wiki/Percent-encoding#Percent-encoding_the_percent_character)
+
+Explicitly, the following characters need to be escaped:
+`!`, `#`, `$`, `%`, `&`, `'`, `(`, `)`, `*`, `+`, `,`, `/`, `:`, `;`, `=`, `?`, `@`, `[`, `]`
+
+It's easiest to always run the URL parts of your DB connection URL (e.g. username, password, etc) through an URL encoder. See the example Python snippets below:
+
+```bash
+$ python3 -c 'import urllib.parse; print(urllib.parse.quote(input("String to encode: "), ""))'
+String to encode: FAKEpassword!#$%&'()*+,/:;=?@[]
+FAKEpassword%21%23%24%25%26%27%28%29%2A%2B%2C%2F%3A%3B%3D%3F%40%5B%5D
+$ python2 -c 'import urllib; print urllib.quote(raw_input("String to encode: "), "")'
+String to encode: FAKEpassword!#$%&'()*+,/:;=?@[]
+FAKEpassword%21%23%24%25%26%27%28%29%2A%2B%2C%2F%3A%3B%3D%3F%40%5B%5D
+$
+```
+
+## Migration Sources
+
+Source drivers read migrations from local or remote sources. [Add a new source?](source/driver.go)
+
+* [Filesystem](source/file) - read from filesystem
+* [io/fs](source/iofs) - read from a Go [io/fs](https://pkg.go.dev/io/fs#FS)
+* [Go-Bindata](source/go_bindata) - read from embedded binary data ([jteeuwen/go-bindata](https://github.com/jteeuwen/go-bindata))
+* [pkger](source/pkger) - read from embedded binary data ([markbates/pkger](https://github.com/markbates/pkger))
+* [GitHub](source/github) - read from remote GitHub repositories
+* [GitHub Enterprise](source/github_ee) - read from remote GitHub Enterprise repositories
+* [Bitbucket](source/bitbucket) - read from remote Bitbucket repositories
+* [Gitlab](source/gitlab) - read from remote Gitlab repositories
+* [AWS S3](source/aws_s3) - read from Amazon Web Services S3
+* [Google Cloud Storage](source/google_cloud_storage) - read from Google Cloud Platform Storage
+
+## CLI usage
+
+* Simple wrapper around this library.
+* Handles ctrl+c (SIGINT) gracefully.
+* No config search paths, no config files, no magic ENV var injections.
+
+[CLI Documentation](cmd/migrate) (includes CLI install instructions)
+
+### Basic usage
+
+```bash
+$ migrate -source file://path/to/migrations -database postgres://localhost:5432/database up 2
+```
+
+### Docker usage
+
+```bash
+$ docker run -v {{ migration dir }}:/migrations --network host migrate/migrate
+    -path=/migrations/ -database postgres://localhost:5432/database up 2
+```
+
+## Use in your Go project
+
+* API is stable and frozen for this release (v3 & v4).
+* Uses [Go modules](https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more) to manage dependencies.
+* To help prevent database corruptions, it supports graceful stops via `GracefulStop chan bool`.
+* Bring your own logger.
+* Uses `io.Reader` streams internally for low memory overhead.
+* Thread-safe and no goroutine leaks.

+
+### Windows
+
+Using [scoop](https://scoop.sh/)
+
+```bash

+
+### Linux (*.deb package)
+
+```bash

+
+#### Versioned
+
+```bash
+$ go get -u -d github.com/golang-migrate/migrate/cmd/migrate
+$ cd $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate
+$ git checkout $TAG  # e.g. v4.1.0
+$ # Go 1.15 and below
+$ go build -tags 'postgres' -ldflags="-X main.Version=$(git describe --tags)" -o $GOPATH/bin/migrate $GOPATH/src/github.com/golang-migrate/migrate/cmd/migrate
+$ # Go 1.16+
+$ go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@$TAG
+```
+
+#### Unversioned
+
+```bash
+$ # Go 1.15 and below

+$ # Go 1.16+
+$ go install -tags 'postgres' github.com/golang-migrate/migrate/v4/cmd/migrate@latest
+```
+
+#### Notes
+
+1. Requires a version of Go that [supports modules](https://golang.org/cmd/go/#hdr-Preliminary_module_support). e.g. Go 1.11+
+1. These examples build the cli which will only work with postgres.  In order
+to build the cli for use with other databases, replace the `postgres` build tag
+with the appropriate database tag(s) for the databases desired.  The tags
+correspond to the names of the sub-packages underneath the
+[`database`](../../database) package.
+1. Similarly to the database build tags, if you need to support other sources, use the appropriate build tag(s).
+1. Support for build constraints will be removed in the future: https://github.com/golang-migrate/migrate/issues/60
+1. For versions of Go 1.15 and lower, [make sure](https://github.com/golang-migrate/migrate/pull/257#issuecomment-705249902) you're not installing the `migrate` CLI from a module. e.g. there should not be any `go.mod` files in your current directory or any directory from your current directory to the root
+
+## Usage
+
+```bash
+$ migrate -help
+Usage: migrate OPTIONS COMMAND [arg...]
+       migrate [ -version | -help ]
+
+Options:
+  -source          Location of the migrations (driver://url)
+  -path            Shorthand for -source=file://path
+  -database        Run migrations against this database (driver://url)
+  -prefetch N      Number of migrations to load in advance before executing (default 10)
+  -lock-timeout N  Allow N seconds to acquire database lock (default 15)
+  -verbose         Print verbose logging
+  -version         Print version
+  -help            Print usage
+
+Commands:
+  create [-ext E] [-dir D] [-seq] [-digits N] [-format] [-tz] NAME
+           Create a set of timestamped up/down migrations titled NAME, in directory D with extension E.
+           Use -seq option to generate sequential up/down migrations with N digits.
+           Use -format option to specify a Go time format string. Note: migrations with the same time cause "duplicate migration version" error.
+           Use -tz option to specify the timezone that will be used when generating non-sequential migrations (defaults: UTC).
+
+  goto V       Migrate to version V
+  up [N]       Apply all or N up migrations
+  down [N] [-all]    Apply all or N down migrations
+        Use -all to apply all down migrations
+  drop [-f]    Drop everything inside database
+        Use -f to bypass confirmation
+  force V      Set version V but don't run migration (ignores dirty state)
+  version      Print current migration version
+```
+
+So let's say you want to run the first two migrations
+
+```bash
+$ migrate -source file://path/to/migrations -database postgres://localhost:5432/database up 2
+```
+
+If your migrations are hosted on github
+
+```bash
+$ migrate -source github://mattes:personal-access-token@mattes/migrate_test \
+    -database postgres://localhost:5432/database down 2
+```
+
+The CLI will gracefully stop at a safe point when SIGINT (ctrl+c) is received.
+Send SIGKILL for immediate halt.
+
+## Reading CLI arguments from somewhere else
+
+### ENV variables
+
+```bash
+$ migrate -database "$MY_MIGRATE_DATABASE"
+```
+
+### JSON files
+
+Check out https://stedolan.github.io/jq/
+
+```bash
+$ migrate -database "$(cat config.json | jq -r '.database')"
+```
+
+### YAML files
+
+```bash
+$ migrate -database "$(cat config/database.yml | ruby -ryaml -e "print YAML.load(STDIN.read)['database']")"
+$ migrate -database "$(cat config/database.yml | python -c 'import yaml,sys;print yaml.safe_load(sys.stdin)["database"]')"
+```

+# Cassandra / ScyllaDB
+
+* `Drop()` method will not work on Cassandra 2.X because it rely on
+system_schema table which comes with 3.X
+* Other methods should work properly but are **not tested**
+* The Cassandra driver (gocql) does not natively support executing multiple statements in a single query. To allow for multiple statements in a single migration, you can use the `x-multi-statement` param. There are two important caveats:
+  * This mode splits the migration text into separately-executed statements by a semi-colon `;`. Thus `x-multi-statement` cannot be used when a statement in the migration contains a string with a semi-colon.
+  * The queries are not executed in any sort of transaction/batch, meaning you are responsible for fixing partial migrations.
+
+**ScyllaDB**
+
+* No additional configuration is required since it is a drop-in replacement for Cassandra.
+* The `Drop()` method` works for ScyllaDB 5.1
+
+
+## Usage
+`cassandra://host:port/keyspace?param1=value&param2=value2`
+
+
+| URL Query  | Default value | Description |
+|------------|-------------|-----------|
+| `x-migrations-table` | schema_migrations | Name of the migrations table |
+| `x-multi-statement` | false | Enable multiple statements to be ran in a single migration (See note above) |
+| `port` | 9042 | The port to bind to  |
+| `consistency` | ALL | Migration consistency
+| `protocol` |  | Cassandra protocol version (3 or 4)
+| `timeout` | 1 minute | Migration timeout
+| `connect-timeout` | 600ms | Initial connection timeout to the cluster |
+| `username` | nil | Username to use when authenticating. |
+| `password` | nil | Password to use when authenticating. |
+| `sslcert` | | Cert file location. The file must contain PEM encoded data. |
+| `sslkey` | | Key file location. The file must contain PEM encoded data. |
+| `sslrootcert` | | The location of the root certificate file. The file must contain PEM encoded data. |
+| `sslmode` | | Whether or not to use SSL (disable\|require\|verify-ca\|verify-full) |
+| `disable-host-lookup`| false | Disable initial host lookup. |
+
+`timeout` is parsed using [time.ParseDuration(s string)](https://golang.org/pkg/time/#ParseDuration)
+
+
+## Upgrading from v1
+
+1. Write down the current migration version from schema_migrations
+2. `DROP TABLE schema_migrations`
+4. Download and install the latest migrate version.
+5. Force the current migration version with `migrate force <current_version>`.

+# ClickHouse
+
+`clickhouse://host:port?username=user&password=password&database=clicks&x-multi-statement=true`
+
+| URL Query  | Description |
+|------------|-------------|
+| `x-migrations-table`| Name of the migrations table |
+| `x-migrations-table-engine`| Engine to use for the migrations table, defaults to TinyLog |
+| `x-cluster-name` | Name of cluster for creating `schema_migrations` table cluster wide |
+| `database` | The name of the database to connect to |
+| `username` | The user to sign in as |
+| `password` | The user's password |
+| `host` | The host to connect to. |
+| `port` | The port to bind to. |
+| `x-multi-statement` | false | Enable multiple statements to be ran in a single migration (See note below) |
+
+## Notes
+
+* The Clickhouse driver does not natively support executing multiple statements in a single query. To allow for multiple statements in a single migration, you can use the `x-multi-statement` param. There are two important caveats:
+  * This mode splits the migration text into separately-executed statements by a semi-colon `;`. Thus `x-multi-statement` cannot be used when a statement in the migration contains a string with a semi-colon.
+  * The queries are not executed in any sort of transaction/batch, meaning you are responsible for fixing partial migrations.
+* Using the default TinyLog table engine for the schema_versions table prevents backing up the table if using the [clickhouse-backup](https://github.com/AlexAkulov/clickhouse-backup) tool. If backing up the database with make sure the migrations are run with `x-migrations-table-engine=MergeTree`.
+* Clickhouse cluster mode is not officially supported, since it's not tested right now, but you can try enabling `schema_migrations` table replication by specifying a `x-cluster-name`:
+  * When `x-cluster-name` is specified, `x-migrations-table-engine` also should be specified. See the docs regarding [replicated table engines](https://clickhouse.tech/docs/en/engines/table-engines/mergetree-family/replication/#table_engines-replication).
+  * When `x-cluster-name` is specified, only the `schema_migrations` table is replicated across the cluster. You still need to write your migrations so that the application tables are replicated within the cluster.
+* If you want to create database inside the migration, you should know, that table which will manage migrations `schema-migrations table` will be in `default` table, so you can't use `USE <database_name>` inside migration. In this case you may not specify the database in the connection string (example you can find [here](examples/migrations/003_create_database.up.sql))

+# CockroachDB tutorial for beginners (insecure cluster)
+
+## Create/configure database
+
+First, let's start a local cluster - follow step 1. and 2. from [the docs](https://www.cockroachlabs.com/docs/stable/start-a-local-cluster.html#step-1-start-the-first-node).
+
+Once you have it, create a database. Here I am going to create a database called `example`.
+Our user here is `cockroach`. We are not going to use a password, since it's not supported for insecure cluster.
+```
+cockroach sql --insecure --host=localhost:26257
+```
+```
+CREATE DATABASE example;
+CREATE USER IF NOT EXISTS cockroach;
+GRANT ALL ON DATABASE example TO cockroach;
+```
+
+When using Migrate CLI we need to pass to database URL. Let's export it to a variable for convenience:
+```
+export COCKROACHDB_URL='cockroachdb://cockroach:@localhost:26257/example?sslmode=disable'
+```
+`sslmode=disable` means that the connection with our database will not be encrypted. This is needed to connect to an insecure node.
+
+**NOTE:** Do not use COCKROACH_URL as a variable name here, it's already in use for discrete parameters and you may run into connection problems. For more info check out [docs](https://www.cockroachlabs.com/docs/stable/connection-parameters.html#connect-using-discrete-parameters).
+
+You can find further description of database URLs [here](README.md#database-urls).
+
+## Create migrations
+Let's create a table called `users`:
+```
+migrate create -ext sql -dir db/migrations -seq create_users_table
+```
+If there were no errors, we should have two files available under `db/migrations` folder:
+- 000001_create_users_table.down.sql
+- 000001_create_users_table.up.sql
+
+Note the `sql` extension that we provided.
+
+In the `.up.sql` file let's create the table:
+```
+CREATE TABLE IF NOT EXISTS example.users
+(
+   user_id INT PRIMARY KEY,
+   username VARCHAR (50) UNIQUE NOT NULL,
+   password VARCHAR (50) NOT NULL,
+   email VARCHAR (300) UNIQUE NOT NULL
+);
+```
+And in the `.down.sql` let's delete it:
+```
+DROP TABLE IF EXISTS example.users;
+```
+By adding `IF EXISTS/IF NOT EXISTS` we are making migrations idempotent - you can read more about idempotency in [getting started](/GETTING_STARTED.md#create-migrations)
+
+## Run migrations
+```
+migrate -database ${COCKROACHDB_URL} -path db/migrations up
+```
+Let's check if the table was created properly by running `cockroach sql --insecure --host=localhost:26257 -e "show columns from example.users;"`.
+The output you are supposed to see:
+```
+  column_name |  data_type   | is_nullable | column_default | generation_expression |                   indices                    | is_hidden
++-------------+--------------+-------------+----------------+-----------------------+----------------------------------------------+-----------+
+  user_id     | INT8         |    false    | NULL           |                       | {primary,users_username_key,users_email_key} |   false
+  username    | VARCHAR(50)  |    false    | NULL           |                       | {users_username_key}                         |   false
+  password    | VARCHAR(50)  |    false    | NULL           |                       | {}                                           |   false
+  email       | VARCHAR(300) |    false    | NULL           |                       | {users_email_key}                            |   false
+(4 rows)
+```
+Now let's check if running reverse migration also works:
+```
+migrate -database ${COCKROACHDB_URL} -path db/migrations down
+```
+Make sure to check if your database changed as expected in this case as well.
+
+## Database transactions
+
+To show database transactions usage, let's create another set of migrations by running:
+```
+migrate create -ext sql -dir db/migrations -seq add_mood_to_users
+```
+Again, it should create for us two migrations files:
+- 000002_add_mood_to_users.down.sql
+- 000002_add_mood_to_users.up.sql
+
+In Cockroach, when we want our queries to be done in a transaction, we need to wrap it with `BEGIN` and `COMMIT` commands, similar to PostgreSQL.
+In our example, we are going to add a column to our database that can only accept enumerable values or NULL.
+Migration up:
+```
+BEGIN;
+
+ALTER TABLE example.users ADD COLUMN mood STRING;
+ALTER TABLE example.users ADD CONSTRAINT check_mood CHECK (mood IN ('happy', 'sad', 'neutral'));
+
+COMMIT;
+```
+Migration down:
+```
+ALTER TABLE example.users DROP COLUMN mood;
+```
+
+Now we can run our new migration and check the database:
+```
+migrate -database ${COCKROACHDB_URL} -path db/migrations up
+cockroach sql --insecure --host=localhost:26257 -e "show columns from example.users;"
+```
+Expected output:
+```
+  column_name |  data_type   | is_nullable | column_default | generation_expression |                   indices                    | is_hidden  
++-------------+--------------+-------------+----------------+-----------------------+----------------------------------------------+-----------+
+  user_id     | INT8         |    false    | NULL           |                       | {primary,users_username_key,users_email_key} |   false    
+  username    | VARCHAR(50)  |    false    | NULL           |                       | {users_username_key}                         |   false    
+  password    | VARCHAR(50)  |    false    | NULL           |                       | {}                                           |   false    
+  email       | VARCHAR(300) |    false    | NULL           |                       | {users_email_key}                            |   false    
+  mood        | STRING       |    true     | NULL           |                       | {}                                           |   false    
+(5 rows)
+```
+
+## Optional: Run migrations within your Go app
+Here is a very simple app running migrations for the above configuration:
+```
+import (
+	"log"
+
+	"github.com/golang-migrate/migrate/v4"
+	_ "github.com/golang-migrate/migrate/v4/database/cockroachdb"
+	_ "github.com/golang-migrate/migrate/v4/source/file"
+)
+
+func main() {
+	m, err := migrate.New(
+		"file://db/migrations",
+		"cockroachdb://cockroach:@localhost:26257/example?sslmode=disable")
+	if err != nil {
+		log.Fatal(err)
+	}
+	if err := m.Up(); err != nil {
+		log.Fatal(err)
+	}
+}
+```
+You can find details [here](README.md#use-in-your-go-project)

+//     and return a driver instance.
+//  3. Add a test that calls database/testing.go:Test()
+//  4. Add own tests for Open(), WithInstance() (when provided) and Close().
+//     All other functions are tested by tests in database/testing.
+//     Saves you some time and makes sure all database drivers behave the same way.
+//  5. Call Register in init().
+//  6. Create a internal/cli/build_<driver-name>.go file
+//  7. Add driver name in 'DATABASE' variable in Makefile
+//
+// Guidelines:
+//   - Don't try to correct user input. Don't assume things.
+//     When in doubt, return an error and explain the situation to the user.
+//   - All configuration input must come from the URL string in func Open()

+# MongoDB
+
+* Driver work with mongo through [db.runCommands](https://docs.mongodb.com/manual/reference/command/)
+* Migrations support json format. It contains array of commands for `db.runCommand`. Every command is executed in separate request to database 
+* All keys have to be in quotes `"`
+* [Examples](./examples)
+
+# Usage
+
+`mongodb://user:password@host:port/dbname?query` (`mongodb+srv://` also works, but behaves a bit differently. See [docs](https://docs.mongodb.com/manual/reference/connection-string/#dns-seedlist-connection-format) for more information)
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| `x-migrations-collection` | `MigrationsCollection` | Name of the migrations collection |
+| `x-transaction-mode` | `TransactionMode` | If set to `true` wrap commands in [transaction](https://docs.mongodb.com/manual/core/transactions). Available only for replica set. Driver is using [strconv.ParseBool](https://golang.org/pkg/strconv/#ParseBool) for parsing|
+| `x-advisory-locking` | `true` | Feature flag for advisory locking, if set to false, disable advisory locking |
+| `x-advisory-lock-collection` | `migrate_advisory_lock` | The name of the collection to use for advisory locking.|
+| `x-advisory-lock-timeout` | `15` | The max time in seconds that migrate will wait to acquire a lock before failing. |
+| `x-advisory-lock-timeout-interval` | `10` | The max time in seconds between attempts to acquire the advisory lock, the lock is attempted to be acquired using an exponential backoff algorithm. |
+| `dbname` | `DatabaseName` | The name of the database to connect to |
+| `user` | | The user to sign in as. Can be omitted |
+| `password` | | The user's password. Can be omitted | 
+| `host` | | The host to connect to |

+# MySQL
+
+`mysql://user:password@tcp(host:port)/dbname?query`
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| `x-migrations-table` | `MigrationsTable` | Name of the migrations table |
+| `x-no-lock` | `NoLock` | Set to `true` to skip `GET_LOCK`/`RELEASE_LOCK` statements. Useful for [multi-master MySQL flavors](https://www.percona.com/doc/percona-xtradb-cluster/LATEST/features/pxc-strict-mode.html#explicit-table-locking). Only run migrations from one host when this is enabled. |
+| `x-statement-timeout` | `StatementTimeout` | Abort any statement that takes more than the specified number of milliseconds, functionally similar to [Server-side SELECT statement timeouts](https://dev.mysql.com/blog-archive/server-side-select-statement-timeouts/) but enforced by the client. Available for all versions of MySQL, not just >=5.7. | 
+| `dbname` | `DatabaseName` | The name of the database to connect to |
+| `user` | | The user to sign in as |
+| `password` | | The user's password | 
+| `host` | | The host to connect to. |
+| `port` | | The port to bind to. |
+| `tls`  | | TLS / SSL encrypted connection parameter; see [go-sql-driver](https://github.com/go-sql-driver/mysql#tls). Use any name (e.g. `migrate`) if you want to use a custom TLS config (`x-tls-` queries). |
+| `x-tls-ca` | | The location of the CA (certificate authority) file. |
+| `x-tls-cert` | | The location of the client certificate file. Must be used with `x-tls-key`. |
+| `x-tls-key` | | The location of the private key file. Must be used with `x-tls-cert`. |
+| `x-tls-insecure-skip-verify` | | Whether or not to use SSL (true\|false) | 
+
+## Use with existing client
+
+If you use the MySQL driver with existing database client, you must create the client with parameter `multiStatements=true`:
+
+```go
+package main
+
+import (
+    "database/sql"
+    
+    _ "github.com/go-sql-driver/mysql"
+    "github.com/golang-migrate/migrate/v4"
+    "github.com/golang-migrate/migrate/v4/database/mysql"
+    _ "github.com/golang-migrate/migrate/v4/source/file"
+)
+
+func main() {
+    db, _ := sql.Open("mysql", "user:password@tcp(host:port)/dbname?multiStatements=true")
+    driver, _ := mysql.WithInstance(db, &mysql.Config{})
+    m, _ := migrate.NewWithDatabaseInstance(
+        "file:///migrations",
+        "mysql", 
+        driver,
+    )
+    
+    m.Steps(2)
+}
+```
+
+## Upgrading from v1
+
+1. Write down the current migration version from schema_migrations
+1. `DROP TABLE schema_migrations`
+2. Wrap your existing migrations in transactions ([BEGIN/COMMIT](https://dev.mysql.com/doc/refman/5.7/en/commit.html)) if you use multiple statements within one migration.
+3. Download and install the latest migrate version.
+4. Force the current migration version with `migrate force <current_version>`.

+# neo4j
+The Neo4j driver (bolt) does not natively support executing multiple statements in a single query. To allow for multiple statements in a single migration, you can use the `x-multi-statement` param. 
+This mode splits the migration text into separately-executed statements by a semi-colon `;`. Thus `x-multi-statement` cannot be used when a statement in the migration contains a string with a semi-colon.
+The queries **should** run in a single transaction, so partial migrations should not be a concern, but this is untested.
+
+
+`neo4j://user:password@host:port/`
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| `x-multi-statement` | `MultiStatement` | Enable multiple statements to be ran in a single migration (See note above) |
+| `user` | Contained within `AuthConfig` | The user to sign in as |
+| `password` | Contained within `AuthConfig` | The user's password |
+| `host` | | The host to connect to. Values that start with / are for unix domain sockets. (default is localhost) |
+| `port` | | The port to bind to. (default is 7687) |
+|  | `MigrationsLabel` | Name of the migrations node label |
+
+## Supported versions
+
+Only Neo4j v3.5+ is [supported](https://github.com/neo4j/neo4j-go-driver/issues/64#issuecomment-625133600)

+## Create migrations
+Let's create nodes called `Users`:
+```
+migrate create -ext cypher -dir db/migrations -seq create_user_nodes
+```
+If there were no errors, we should have two files available under `db/migrations` folder:
+- 000001_create_user_nodes.down.cypher
+- 000001_create_user_nodes.up.cypher
+
+Note the `cypher` extension that we provided.
+
+In the `.up.cypher` file let's create the table:
+```
+CREATE (u1:User {name: "Peter"})
+CREATE (u2:User {name: "Paul"})
+CREATE (u3:User {name: "Mary"})
+```
+And in the `.down.sql` let's delete it:
+```
+MATCH (u:User) WHERE u.name IN ["Peter", "Paul", "Mary"] DELETE u
+```
+Ideally your migrations should be idempotent. You can read more about idempotency in [getting started](GETTING_STARTED.md#create-migrations)
+
+## Run migrations
+```
+migrate -database ${NEO4J_URL} -path db/migrations up
+```
+Let's check if the table was created properly by running `bin/cypher-shell -u neo4j -p password`, then `neo4j> MATCH (u:User)`
+The output you are supposed to see:
+```
++-----------------------------------------------------------------+
+| u                                                               |
++-----------------------------------------------------------------+
+| (:User {name: "Peter")                                          |
+| (:User {name: "Paul")                                           |
+| (:User {name: "Mary")                                           |
++-----------------------------------------------------------------+
+```
+Great! Now let's check if running reverse migration also works:
+```
+migrate -database ${NEO4J_URL} -path db/migrations down
+```
+Make sure to check if your database changed as expected in this case as well.
+
+## Database transactions
+
+To show database transactions usage, let's create another set of migrations by running:
+```
+migrate create -ext cypher -dir db/migrations -seq add_mood_to_users
+```
+Again, it should create for us two migrations files:
+- 000002_add_mood_to_users.down.cypher
+- 000002_add_mood_to_users.up.cypher
+
+In Neo4j, when we want our queries to be done in a transaction, we need to wrap it with `:BEGIN` and `:COMMIT` commands.
+Migration up:
+```
+:BEGIN
+
+MATCH (u:User)
+SET u.mood = "Cheery"
+
+:COMMIT
+```
+Migration down:
+```
+:BEGIN
+
+MATCH (u:User)
+SET u.mood = null
+
+:COMMIT
+```
+
+## Optional: Run migrations within your Go app
+Here is a very simple app running migrations for the above configuration:
+```
+import (
+	"log"
+
+	"github.com/golang-migrate/migrate/v4"
+	_ "github.com/golang-migrate/migrate/v4/database/neo4j"
+	_ "github.com/golang-migrate/migrate/v4/source/file"
+)
+
+func main() {
+	m, err := migrate.New(
+		"file://db/migrations",
+		"neo4j://neo4j:password@localhost:7687/")
+	if err != nil {
+		log.Fatal(err)
+	}
+	if err := m.Up(); err != nil {
+		log.Fatal(err)
+	}
+}
+```

+# pgx
+
+This package is for [pgx/v4](https://pkg.go.dev/github.com/jackc/pgx/v4). A backend for the newer [pgx/v5](https://pkg.go.dev/github.com/jackc/pgx/v5) is [also available](v5).
+
+`pgx://user:password@host:port/dbname?query`
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| `x-migrations-table` | `MigrationsTable` | Name of the migrations table |
+| `x-migrations-table-quoted` | `MigrationsTableQuoted` | By default, migrate quotes the migration table for SQL injection safety reasons. This option disable quoting and naively checks that you have quoted the migration table name. e.g. `"my_schema"."schema_migrations"` |
+| `x-statement-timeout` | `StatementTimeout` | Abort any statement that takes more than the specified number of milliseconds |
+| `x-multi-statement` | `MultiStatementEnabled` | Enable multi-statement execution (default: false) |
+| `x-multi-statement-max-size` | `MultiStatementMaxSize` | Maximum size of single statement in bytes (default: 10MB) |
+| `x-lock-strategy` | `LockStrategy` | Strategy used for locking during migration (default: advisory) |
+| `x-lock-table` | `LockTable` | Name of the table which maintains the migration lock (default: schema_lock) |
+| `dbname` | `DatabaseName` | The name of the database to connect to |
+| `search_path` | | This variable specifies the order in which schemas are searched when an object is referenced by a simple name with no schema specified. |
+| `user` | | The user to sign in as |
+| `password` | | The user's password |
+| `host` | | The host to connect to. Values that start with / are for unix domain sockets. (default is localhost) |
+| `port` | | The port to bind to. (default is 5432) |
+| `fallback_application_name` | | An application_name to fall back to if one isn't provided. |
+| `connect_timeout` | | Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely. |
+| `sslcert` | | Cert file location. The file must contain PEM encoded data. |
+| `sslkey` | | Key file location. The file must contain PEM encoded data. |
+| `sslrootcert` | | The location of the root certificate file. The file must contain PEM encoded data. |
+| `sslmode` | | Whether or not to use SSL (disable\|require\|verify-ca\|verify-full) |
+
+
+## Upgrading from v1
+
+1. Write down the current migration version from schema_migrations
+1. `DROP TABLE schema_migrations`
+2. Wrap your existing migrations in transactions ([BEGIN/COMMIT](https://www.postgresql.org/docs/current/static/transaction-iso.html)) if you use multiple statements within one migration.
+3. Download and install the latest migrate version.
+4. Force the current migration version with `migrate force <current_version>`.
+
+## Multi-statement mode
+
+In PostgreSQL running multiple SQL statements in one `Exec` executes them inside a transaction. Sometimes this
+behavior is not desirable because some statements can be only run outside of transaction (e.g.
+`CREATE INDEX CONCURRENTLY`). If you want to use `CREATE INDEX CONCURRENTLY` without activating multi-statement mode
+you have to put such statements in a separate migration files.

+# pgx
+
+This package is for [pgx/v5](https://pkg.go.dev/github.com/jackc/pgx/v5). A backend for the older [pgx/v4](https://pkg.go.dev/github.com/jackc/pgx/v4). is [also available](..).
+
+`pgx5://user:password@host:port/dbname?query`
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| `x-migrations-table` | `MigrationsTable` | Name of the migrations table |
+| `x-migrations-table-quoted` | `MigrationsTableQuoted` | By default, migrate quotes the migration table for SQL injection safety reasons. This option disable quoting and naively checks that you have quoted the migration table name. e.g. `"my_schema"."schema_migrations"` |
+| `x-statement-timeout` | `StatementTimeout` | Abort any statement that takes more than the specified number of milliseconds |
+| `x-multi-statement` | `MultiStatementEnabled` | Enable multi-statement execution (default: false) |
+| `x-multi-statement-max-size` | `MultiStatementMaxSize` | Maximum size of single statement in bytes (default: 10MB) |
+| `dbname` | `DatabaseName` | The name of the database to connect to |
+| `search_path` | | This variable specifies the order in which schemas are searched when an object is referenced by a simple name with no schema specified. |
+| `user` | | The user to sign in as |
+| `password` | | The user's password |
+| `host` | | The host to connect to. Values that start with / are for unix domain sockets. (default is localhost) |
+| `port` | | The port to bind to. (default is 5432) |
+| `fallback_application_name` | | An application_name to fall back to if one isn't provided. |
+| `connect_timeout` | | Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely. |
+| `sslcert` | | Cert file location. The file must contain PEM encoded data. |
+| `sslkey` | | Key file location. The file must contain PEM encoded data. |
+| `sslrootcert` | | The location of the root certificate file. The file must contain PEM encoded data. |
+| `sslmode` | | Whether or not to use SSL (disable\|require\|verify-ca\|verify-full) |
+
+
+## Upgrading from v1
+
+1. Write down the current migration version from schema_migrations
+1. `DROP TABLE schema_migrations`
+2. Wrap your existing migrations in transactions ([BEGIN/COMMIT](https://www.postgresql.org/docs/current/static/transaction-iso.html)) if you use multiple statements within one migration.
+3. Download and install the latest migrate version.
+4. Force the current migration version with `migrate force <current_version>`.
+
+## Multi-statement mode
+
+In PostgreSQL running multiple SQL statements in one `Exec` executes them inside a transaction. Sometimes this
+behavior is not desirable because some statements can be only run outside of transaction (e.g.
+`CREATE INDEX CONCURRENTLY`). If you want to use `CREATE INDEX CONCURRENTLY` without activating multi-statement mode
+you have to put such statements in a separate migration files.

+|------------|---------------------|-------------|
+| `x-migrations-table` | `MigrationsTable` | Name of the migrations table |
+| `x-migrations-table-quoted` | `MigrationsTableQuoted` | By default, migrate quotes the migration table for SQL injection safety reasons. This option disable quoting and naively checks that you have quoted the migration table name. e.g. `"my_schema"."schema_migrations"` |
+| `x-statement-timeout` | `StatementTimeout` | Abort any statement that takes more than the specified number of milliseconds |
+| `x-multi-statement` | `MultiStatementEnabled` | Enable multi-statement execution (default: false) |
+| `x-multi-statement-max-size` | `MultiStatementMaxSize` | Maximum size of single statement in bytes (default: 10MB) |
+| `dbname` | `DatabaseName` | The name of the database to connect to |
+| `search_path` | | This variable specifies the order in which schemas are searched when an object is referenced by a simple name with no schema specified. |
+| `user` | | The user to sign in as |
+| `password` | | The user's password | 
+| `host` | | The host to connect to. Values that start with / are for unix domain sockets. (default is localhost) |
+| `port` | | The port to bind to. (default is 5432) |
+| `fallback_application_name` | | An application_name to fall back to if one isn't provided. |
+| `connect_timeout` | | Maximum wait for connection, in seconds. Zero or not specified means wait indefinitely. |

+| `sslkey` | | Key file location. The file must contain PEM encoded data. |
+| `sslrootcert` | | The location of the root certificate file. The file must contain PEM encoded data. | 
+| `sslmode` | | Whether or not to use SSL (disable\|require\|verify-ca\|verify-full) |
+
+
+## Upgrading from v1
+
+1. Write down the current migration version from schema_migrations
+1. `DROP TABLE schema_migrations`
+2. Wrap your existing migrations in transactions ([BEGIN/COMMIT](https://www.postgresql.org/docs/current/static/transaction-iso.html)) if you use multiple statements within one migration.
+3. Download and install the latest migrate version.
+4. Force the current migration version with `migrate force <current_version>`.
+
+## Multi-statement mode
+
+In PostgreSQL running multiple SQL statements in one `Exec` executes them inside a transaction. Sometimes this
+behavior is not desirable because some statements can be only run outside of transaction (e.g.
+`CREATE INDEX CONCURRENTLY`). If you want to use `CREATE INDEX CONCURRENTLY` without activating multi-statement mode
+you have to put such statements in a separate migration files.

+# PostgreSQL tutorial for beginners
+
+## Create/configure database
+
+For the purpose of this tutorial let's create PostgreSQL database called `example`.
+Our user here is `postgres`, password `password`, and host is `localhost`.
+```
+psql -h localhost -U postgres -w -c "create database example;"
+```
+When using Migrate CLI we need to pass to database URL. Let's export it to a variable for convenience:
+```
+export POSTGRESQL_URL='postgres://postgres:password@localhost:5432/example?sslmode=disable'
+```
+`sslmode=disable` means that the connection with our database will not be encrypted. Enabling it is left as an exercise.
+
+You can find further description of database URLs [here](README.md#database-urls).
+
+## Create migrations
+Let's create table called `users`:
+```
+migrate create -ext sql -dir db/migrations -seq create_users_table
+```
+If there were no errors, we should have two files available under `db/migrations` folder:
+- 000001_create_users_table.down.sql
+- 000001_create_users_table.up.sql
+
+Note the `sql` extension that we provided.
+
+In the `.up.sql` file let's create the table:
+```sql
+CREATE TABLE IF NOT EXISTS users(
+   user_id serial PRIMARY KEY,
+   username VARCHAR (50) UNIQUE NOT NULL,
+   password VARCHAR (50) NOT NULL,
+   email VARCHAR (300) UNIQUE NOT NULL
+);
+```
+And in the `.down.sql` let's delete it:
+```sql
+DROP TABLE IF EXISTS users;
+```
+By adding `IF EXISTS/IF NOT EXISTS` we are making migrations idempotent - you can read more about idempotency in [getting started](../../GETTING_STARTED.md#create-migrations)
+
+## Run migrations
+```
+migrate -database ${POSTGRESQL_URL} -path db/migrations up
+```
+Let's check if the table was created properly by running `psql example -c "\d users"`.
+The output you are supposed to see:
+```
+                                    Table "public.users"
+  Column  |          Type          |                        Modifiers                        
+----------+------------------------+---------------------------------------------------------
+ user_id  | integer                | not null default nextval('users_user_id_seq'::regclass)
+ username | character varying(50)  | not null
+ password | character varying(50)  | not null
+ email    | character varying(300) | not null
+Indexes:
+    "users_pkey" PRIMARY KEY, btree (user_id)
+    "users_email_key" UNIQUE CONSTRAINT, btree (email)
+    "users_username_key" UNIQUE CONSTRAINT, btree (username)
+```
+Great! Now let's check if running reverse migration also works:
+```
+migrate -database ${POSTGRESQL_URL} -path db/migrations down
+```
+Make sure to check if your database changed as expected in this case as well.
+
+## Database transactions
+
+To show database transactions usage, let's create another set of migrations by running:
+```
+migrate create -ext sql -dir db/migrations -seq add_mood_to_users
+```
+Again, it should create for us two migrations files:
+- 000002_add_mood_to_users.down.sql
+- 000002_add_mood_to_users.up.sql
+
+In Postgres, when we want our queries to be done in a transaction, we need to wrap it with `BEGIN` and `COMMIT` commands.
+In our example, we are going to add a column to our database that can only accept enumerable values or NULL.
+Migration up:
+```sql
+BEGIN;
+
+CREATE TYPE enum_mood AS ENUM (
+	'happy',
+	'sad',
+	'neutral'
+);
+ALTER TABLE users ADD COLUMN mood enum_mood;
+
+COMMIT;
+```
+Migration down:
+```sql
+BEGIN;
+
+ALTER TABLE users DROP COLUMN mood;
+DROP TYPE enum_mood;
+
+COMMIT;
+```
+
+Now we can run our new migration and check the database:
+```
+migrate -database ${POSTGRESQL_URL} -path db/migrations up
+psql example -c "\d users"
+```
+Expected output:
+```
+                                    Table "public.users"
+  Column  |          Type          |                        Modifiers                        
+----------+------------------------+---------------------------------------------------------
+ user_id  | integer                | not null default nextval('users_user_id_seq'::regclass)
+ username | character varying(50)  | not null

+## Optional: Run migrations within your Go app
+Here is a very simple app running migrations for the above configuration:
+```go
+import (
+	"log"
+
+	"github.com/golang-migrate/migrate/v4"
+	_ "github.com/golang-migrate/migrate/v4/database/postgres"
+	_ "github.com/golang-migrate/migrate/v4/source/file"
+)
+
+func main() {
+	m, err := migrate.New(
+		"file://db/migrations",
+		"postgres://postgres:postgres@localhost:5432/example?sslmode=disable")
+	if err != nil {
+		log.Fatal(err)
+	}
+	if err := m.Up(); err != nil {
+		log.Fatal(err)
+	}
+}
+```
+You can find details [here](README.md#use-in-your-go-project)
+
+## Fix issue where migrations run twice
+
+When the schema and role names are the same, you might run into issues if you create this schema using migrations.
+This is caused by the fact that the [default `search_path`](https://www.postgresql.org/docs/current/ddl-schemas.html#DDL-SCHEMAS-PATH) is `"$user", public`.
+In the first run (with an empty database) the migrate table is created in `public`.
+When the migrations create the `$user` schema, the next run will store (a new) migrate table in this schema (due to order of schemas in `search_path`) and tries to apply all migrations again (most likely failing).
+
+To solve this you need to change the default `search_path` by removing the `$user` component, so the migrate table is always stored in the (available) `public` schema.
+This can be done using the [`search_path` query parameter in the URL](https://github.com/jexia/migrate/blob/fix-postgres-version-table/database/postgres/README.md#postgres).
+
+For example to force the migrations table in the public schema you can use:
+```
+export POSTGRESQL_URL='postgres://postgres:password@localhost:5432/example?sslmode=disable&search_path=public'
+```
+
+Note that you need to explicitly add the schema names to the table names in your migrations when you to modify the tables of the non-public schema.
+
+Alternatively you can add the non-public schema manually (before applying the migrations) if that is possible in your case and let the tool store the migrations table in this schema as well.

+# rqlite
+
+`rqlite://admin:secret@server1.example.com:4001/?level=strong&timeout=5`
+
+The `rqlite` url scheme is used for both secure and insecure connections. If connecting to an insecure database, pass `x-connect-insecure` in your URL query, or use `WithInstance` to pass an established connection.
+
+The migrations table name is configurable through the `x-migrations-table` URL query parameter, or by using `WithInstance` and passing `MigrationsTable` through `Config`.
+
+Other connect parameters are directly passed through to the database driver. For examples of connection strings, see https://github.com/rqlite/gorqlite#examples.
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| `x-connect-insecure` | n/a: set on instance | Boolean to indicate whether to use an insecure connection. Defaults to `false`. |
+| `x-migrations-table` | `MigrationsTable` | Name of the migrations table.  Defaults to `schema_migrations`. |
+
+## Notes
+
+* Uses the https://github.com/rqlite/gorqlite driver

+# Google Cloud Spanner
+
+## Usage
+
+See [Google Spanner Documentation](https://cloud.google.com/spanner/docs) for
+more details.
+
+The DSN must be given in the following format.
+
+`spanner://projects/{projectId}/instances/{instanceId}/databases/{databaseName}?param=true`
+
+as described in [README.md#database-urls](../../README.md#database-urls)
+
+| Param | WithInstance Config | Description |
+| ----- | ------------------- | ----------- |
+| `x-migrations-table` | `MigrationsTable` | Name of the migrations table |
+| `x-clean-statements` | `CleanStatements` | Whether to parse and clean DDL statements before running migration towards Spanner (Required for comments and multiple statements) |
+| `url` | `DatabaseName` | The full path to the Spanner database resource. If provided as part of `Config` it must not contain a scheme or query string to match the format `projects/{projectId}/instances/{instanceId}/databases/{databaseName}`|
+| `projectId` || The Google Cloud Platform project id
+| `instanceId` || The id of the instance running Spanner
+| `databaseName` || The name of the Spanner database
+
+> **Note:** Google Cloud Spanner migrations can take a considerable amount of 
+> time. The migrations provided as part of the example take about 6 minutes to 
+> run on a small instance.
+>
+> ```log
+> 1481574547/u create_users_table (21.354507597s)
+> 1496539702/u add_city_to_users (41.647359754s)
+> 1496601752/u add_index_on_user_emails (2m12.155787369s)
+> 1496602638/u create_books_table (2m30.77299181s)
+
+## DDL with comments
+
+At the moment the GCP Spanner backed does not seem to allow for comments (See https://issuetracker.google.com/issues/159730604)
+so in order to be able to use migration with DDL containing comments `x-clean-statements` is required
+
+## Multiple statements
+
+In order to be able to use more than 1 DDL statement in the same migration file, the file has to be parsed and therefore the `x-clean-statements` flag is required
+
+## Testing
+
+To unit test the `spanner` driver, `SPANNER_DATABASE` needs to be set. You'll
+need to sign-up to Google Cloud Platform (GCP) and have a running Spanner
+instance since it is not possible to run Google Spanner outside GCP.

+| `encrypt` | | `disable` - Data send between client and server is not encrypted. `false` - Data sent between client and server is not encrypted beyond the login packet (Default). `true` - Data sent between client and server is encrypted. |
+| `app+name` || The application name (default is go-mssqldb). |
+| `useMsi` | | `true` - Use Azure MSI Authentication for connecting to Sql Server. Must be running from an Azure VM/an instance with MSI enabled. `false` - Use password authentication (Default). See [here for Azure MSI Auth details](https://docs.microsoft.com/en-us/azure/app-service/app-service-web-tutorial-connect-msi). NOTE: Since this cannot be tested locally, this is not officially supported.
+
+See https://github.com/microsoft/go-mssqldb for full parameter list.
+
+## Driver Support
+
+### Which go-mssqldb driver to us?
+
+Please note that the deprecated `mssql` driver is not supported. Please use the newer `sqlserver` driver.  
+See https://github.com/microsoft/go-mssqldb#deprecated for more information.
+
+### Official Support by migrate
+
+Versions of MS SQL Server 2019 newer than CTP3.1 are not officially supported since there are issues testing against the Docker image.
+For more info, see: https://github.com/golang-migrate/migrate/issues/160#issuecomment-522433269

+// Driver is the interface every source driver must implement.
+//
+// How to implement a source driver?
+//  1. Implement this interface.
+//  2. Optionally, add a function named `WithInstance`.
+//     This function should accept an existing source instance and a Config{} struct
+//     and return a driver instance.
+//  3. Add a test that calls source/testing.go:Test()
+//  4. Add own tests for Open(), WithInstance() (when provided) and Close().
+//     All other functions are tested by tests in source/testing.
+//     Saves you some time and makes sure all source drivers behave the same way.
+//  5. Call Register in init().
+//
+// Guidelines:
+//   - All configuration input must come from the URL string in func Open()
+//     or the Config{} struct in WithInstance. Don't os.Getenv().
+//   - Drivers are supposed to be read only.
+//   - Ideally don't load any contents (into memory) in Open or WithInstance.

+## GitHub Enterprise Edition
+
+This driver is catered for those who run GitHub Enterprise under private infrastructure.
+
+The below URL scheme illustrates how to source migration files from GitHub Enterprise.
+
+GitHub client for Go requires API and Uploads endpoint hosts in order to create an instance of GitHub Enterprise Client. We're making an assumption that the API and Uploads are available under `https://api.*` and `https://uploads.*` respectively. [GitHub Enterprise Installation Guide](https://help.github.com/en/enterprise/2.15/admin/installation/enabling-subdomain-isolation) recommends that you enable Subdomain isolation feature.
+
+`github-ee://user:personal-access-token@host/owner/repo/path?verify-tls=true#ref`
+
+| URL Query  | WithInstance Config | Description |
+|------------|---------------------|-------------|
+| user | | The username of the user connecting |
+| personal-access-token | | Personal access token from your GitHub Enterprise instance |
+| owner | | the repo owner |
+| repo | | the name of the repository |
+| path | | path in repo to migrations |
+| ref | | (optional) can be a SHA, branch, or tag |
+| verify-tls | | (optional) defaults to `true`. This option sets `tls.Config.InsecureSkipVerify` accordingly |

+## Usage
+
+
+
+### Read bindata with NewWithSourceInstance
+
+```shell
+go get -u github.com/jteeuwen/go-bindata/...
+cd examples/migrations && go-bindata -pkg migrations .
+```
+
+```go
+import (
+  "github.com/golang-migrate/migrate/v4"
+  "github.com/golang-migrate/migrate/v4/source/go_bindata"
+  "github.com/golang-migrate/migrate/v4/source/go_bindata/examples/migrations"
+)
+
+func main() {
+  // wrap assets into Resource
+  s := bindata.Resource(migrations.AssetNames(),
+    func(name string) ([]byte, error) {
+      return migrations.Asset(name)
+    })
+    
+  d, err := bindata.WithInstance(s)
+  m, err := migrate.NewWithSourceInstance("go-bindata", d, "database://foobar")
+  m.Up() // run your migrations and handle the errors above of course
+}
+```
+
+### Read bindata with URL (todo)
+
+This will restore the assets in a tmp directory and then
+proxy to source/file. go-bindata must be in your `$PATH`.
+
+```
+migrate -source go-bindata://examples/migrations/bindata.go
+```

+# httpfs
+
+## Usage
+
+This package could be used to create new migration source drivers that uses
+`http.FileSystem` to read migration files.
+
+Struct `httpfs.PartialDriver` partly implements the `source.Driver` interface. It has all
+the methods except for `Open()`. Embedding this struct and adding `Open()` method
+allows users of this package to create new migration sources. Example:
+
+```go
+struct mydriver {
+        httpfs.PartialDriver
+}
+
+func (d *mydriver) Open(url string) (source.Driver, error) {
+	var fs http.FileSystem
+	var path string
+	var ds mydriver
+
+	// acquire fs and path from url
+	// set-up ds if necessary
+
+	if err := ds.Init(fs, path); err != nil {
+		return nil, err
+	}
+	return &ds, nil
+}
+```
+
+This package also provides a simple `source.Driver` implementation that works
+with `http.FileSystem` provided by the user of this package. It is created with
+`httpfs.New()` call.
+
+Example of using `http.Dir()` to read migrations from `sql` directory:
+
+```go
+	src, err := httpfs.New(http.Dir("sql"))
+	if err != nil {
+		// do something
+	}
+	m, err := migrate.NewWithSourceInstance("httpfs", src, "database://url")
+	if err != nil {
+		// do something
+	}
+        err = m.Up()
+	...
+```
