databases/py-pgmigrate 1.0.9_1 DragonFly

PGmigrate is a database migration tool developed by Yandex.

PGmigrate has the following key-features:

• Transactional and nontransactional migrations: you can enjoy whole power of PostgreSQL DDL
• Callbacks: you can run some DDL on specific steps of migration process (e.g. drop some code before executing migrations, and create it back after migrations were applied)
• Online migrations: you can execute series of transactional migrations and callbacks in a single transaction (so, if something goes wrong simple ROLLBACK will bring you in consistent state)
