selfcheck when evaluating supaschema against an existing database or after upgrading the engine.
The command extracts a live catalog, re-renders the modeled SQL, re-extracts it, and reports identity normalization gaps.
Use this when
- You are validating catalog normalization.
- A provider-specific object shape may need investigation.
- An upgrade should be checked against a real database.
- You need diagnostics for engine parity work.
Run it
selfcheck is a diagnostic tool, not a deployment gate. Review mismatches before deciding whether they matter.
