database schema changes in production, what's your strategy

we got more product updates happening all the time, and that means the database schema changes a lot too. rolling back a bad schema change can be a nightmare, and man, weve had some real painful moments with it. whats your go-to strategy for handling schema migrations in production. are you using tools like flyway or liquibase. do you think blue-green deployments for the database are better. im curious to hear what works for other folks.
