Transactional Migrations

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.

Over and above installing the plugin, no further action is required for the transactions to take effect.
