Ask HN: What does hackernews use to manage database schemas?

What do you guys use to track your database schema changes? Personally I’ve used custom scripts and alembic before. Recently I’ve been looking at some products like redgate https://www.red-gate.com and https://flywaydb.org. I’ve also found smaller services: https://hyperclone.com and many stack threads: https://stackoverflow.com/questions/175451/how-do-you-version-your-database-schema. It seems like most of the solutions have a large overhead and there seems to be a lack of consensus about how to track schema changes. What do you guys do/use to manage database schemas?
