# Multigres compatibility

Where Multigres-backed Postgres projects differ from standard Postgres.

Multigres targets full compatibility with standard Postgres, verified against the [`pg_regress`](https://www.postgresql.org/docs/current/regress.html) test suite. See the [Multigres documentation](https://multigres.com/docs) for lower-level architecture and compatibility details, and the [Multigres overview](https://supabase.com/docs/guides/database/multigres#whats-not-included-in-the-alpha) for what's not yet supported during the Public Alpha.
