Transactional Migrations Plugin

I wrote a while ago on utilising transactional DDL in your ruby on rails migration scripts so I decided to create a plugin.

In a nutshell:

Transactional Migrations is a plugin that ensures your migration scripts – both up and down – run within a transaction. When used in conjunction with a database that supports transactional Data Definition Language (DDL) – such as PostgreSQL – this ensures that if any statement within your migration script fails, the entire script is rolled-back.
