Show HN: Zero-downtime PostgreSQL migrations for Ruby on Rails
While it hasn't been updated in a while, fundamentally https://github.com/pombredanne/django-zerodowntime would be a base for building similar check logic in a DB agnostic way on Django. It has some of the most important checks in place, but could obviously do with adding more sophisticated checks.
For Django users using PostgreSQL you can use https://github.com/antonioIrizar/django-check-migration-wtf or https://github.com/yandex/zero-downtime-migrations or https://github.com/tbicr/django-pg-zero-downtime-migrations to provide similar functionality to the library this post links to, depending on your exact use case of course.

Show HN: Zero-downtime PostgreSQL migrations for Ruby on Rails
This is cool. We use strong_migrations but I’ll check this out. I love the idea of an enforced pattern for background data migrations.
While I’m here a shameless plug for a gem we built that we’ve found incredibly helpful for safer migrations - https://github.com/TandaHQ/migration_signature
It adds a CI check to guarantee the migrations you tested in development are actually the migrations that run in production.
What are some alternatives?
pg-osc - Easy CLI tool for making zero downtime schema changes and backfills in PostgreSQL
safe-pg-migrations - Make your PostgreSQL migrations safe
django-zerodowntime - django migration utilities for zero downtime continuous delivery
online_migrations - Catch unsafe PostgreSQL migrations in development and run them easier in production (code helpers for table/column renaming, changing column type, adding columns with default, background migrations, etc).
nandi - Fear free PostgreSQL migrations for Rails
django-check-migration-wtf - check migrations of django to work on enviroment zero downtime
zero-downtime-migrations - Apply Django migrations on PostgreSql without long locks on tables
