PGmigrate

PostgreSQL migrations made easy

Overview

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)

pip install yandex-pgmigrate

Tests require running PostgreSQL instance with superuser (to create/drop dbs). You could setup this yourself and use tox to start tests:

tox

Second option is to use docker and make:

make test
