Migrations

Minimal, explicit schema versioning for PostgreSQL and MySQL — no auto-magic, no bulk rollback.

• Create migration scaffolds a timestamped up/down file pair tied to a connection profile.
• Apply runs all pending migrations in order and records applied state in a tracking table (schema_migrations) inside the target database. A mid-run failure leaves the tracking table accurate — the failed migration is not marked applied — and surfaces the underlying database error.
• Rollback reverts exactly one migration step at a time; there is no bulk rollback by design.

A dedicated migrations panel lists pending and applied migrations per connection, with apply/rollback actions available directly from the UI.
