### PostgreSQL migrations for Erlang

---

Simple utility to add migrations for Erlang projects. It doesn't have any database abstraction, you'll still operate with plain SQL and it only supports PostgreSQL (using pgsql or epgsql library). _Inspired by [erlang-sql-migrations](https://github.com/spawngrid/erlang-sql-migrations) by spawngrid_.

---

#### Use

In order to use the tool one writes 'migration' files. Most important thing here is to name in the order of their versioning, like this: `[timestamp]_name.sql`.

```sql

-- priv/migrations/1423733547_users.sql

-- :up

CREATE TABLE users();

-- :down

DROP TABLE users;

```

```erlang

pgsql_migration:migrate(Conn, "priv/migrations").

```

You can rename pgsql driver, if you use [epgsql](https://github.com/epgsql/epgsql) 3.0 or newer:

```erlang

pgsql_migration:use_driver(epgsql).

```
