Enable safe migrations on a production branch
branches
// what it does
Turns on safe migrations for a Vitess production branch: direct DDL (ALTER/CREATE/DROP) is rejected, forcing every schema change through a deploy request with its linting, review, online rollout, and revert window. This is the guard rail that makes the whole PlanetScale workflow safe.
// shell
$ pscale branch safe-migrations enable mydb main$ pscale branch safe-migrations disable mydb main// gotcha
With safe migrations on, your ORM's auto-migrate (drizzle-kit push, prisma db push, Rails migrate against prod) will fail by design — point those tools at a dev branch and let a deploy request carry the change to production.
