erlang_migrate — database migration library modeled after golang-migrate/v4.

Quick Start

  Config = #{
      conn  => Conn,           % epgsql connection pid
      dir   => "priv/migrations",
      table => <<"schema_migrations">>,  % optional
      lock_id => 7369284       % optional, auto-derived from table name
  },
  ok = erlang_migrate:up(Config).

File naming

Migrations live in dir as pairs: {version}_{title}.up.sql {version}_{title}.down.sql (optional — skipping makes down/2 fail)

version must be a positive integer, e.g. 1, 100, 20240101120000.
