Security Posture (2)

A listing is not an endorsement. Review the flags before connecting.

Provenance

Before you trust this

Limitations: The reference server issues raw SQL. Connect with a role that only has SELECT on the schemas intended, and prefer a replica. Do not point it at production with a superuser.
