For me, this is the part where Supabase being purely a Postgres implementation is a real strength. Supabase gives you access to the underlying database directly via a standard Postgres connection, so you can use literally any tool you want for database migrations. Downside to the direct access being that there's no pretty Web UI for it - but I think that's both a pro and con (it sometimes bothers me how much effort they put into their UI, from an purely opportunity-cost perspective).
