migrate

Overview ¶

Command migrate applies database migrations in order and records what it did.

Migrations are forward-only and each runs in its own transaction, so a failure leaves the schema at the last complete migration rather than half-applied (db/migrations/README.md).

It is deliberately small. A migration tool that can roll back encourages destructive down-migrations, and plan section 16.2 requires backwards compatible changes plus a pre-deploy backup instead.
