Catch the database migration that locks or rewrites your production table, before it reaches production.
-- looks fine in review, locks your busiest table in prod:
ALTER TABLE users ALTER COLUMN email SET NOT NULL;
-- the safe rewrite the auditor points you to:
ADD CONSTRAINT c CHECK (email IS NOT NULL) NOT VALID; VALIDATE CONSTRAINT c; then SET NOT NULL;A static auditor for Flyway and Liquibase that flags each production hazard with the reason and the safe rewrite. It parses your migration with the real PostgreSQL parser, cites an official source for every rule, and runs as a CLI, a CI gate, or a Claude Code skill. It never connects to your database. One-time, EUR 14.99.
