runMigrations :: Connection -> [Change PGMigration] -> IO (Either String ()) Source
Takes the list of all migrations, removes the ones that have
already run and runs them. Use this instead of migrate.
getChangeHistory :: Connection -> IO [ChangeHistory] Source
Get all changes from schema_migrations table for all the migrations that have previously run.
getChangeNameHistory :: Connection -> IO [ChangeName] Source
Get just the names of all changes from schema_migrations for migrations that have previously run.
