pg_migrations

github.com/mylescarick/pg_migrations

DESCRIPTION:

Adds migration helpers to allow for postgres-specific stuff like real constraints

FEATURES/PROBLEMS:

Add and remove foreign keys (with optional CASCADE DELETE)
Add and remove unique constraints
Set / unset mandatory columns

SYNOPSIS:

ActiveRecord migrations are fine when we’re just using features supported across MySQL, SQLite, Postgres, etc… but if you’re after the added security of ‘real’ referential integrity, etc then you’re going to be using Postgres.

These helpers provide a simple way to keep your migrations free from hand-written SQL, and make it easy to use the postgres coolness that will help keep your data reliable.

REQUIREMENTS:

Use Postgres >= 8.1

INSTALL:

sudo gem install mylescarrick-pg_migrations
