Peter Eisentraut	d2028e9bbc	postgres_fdw: Fix tests on some Windows variants The tests introduced by commit `76563f88cf` only work when Unix-domain sockets are available. This is optional on Windows, and buildfarm member drongo runs without them. To fix, skip the test if Unix-domain sockets are not enabled.	9 months ago
Peter Eisentraut	76563f88cf	postgres_fdw: improve security checks SCRAM pass-through should not bypass the FDW security check as it was implemented for postgres_fdw in commit `761c79508e`. This commit improves the security check by adding new SCRAM pass-through checks to ensure that the required SCRAM connection options are not overwritten by the user mapping or foreign server options. This is meant to match the security requirements for a password-using connection. Since libpq has no SCRAM-specific equivalent of PQconnectionUsedPassword(), we enforce this instead by making the use_scram_passthrough option of postgres_fdw imply require_auth=scram-sha-256. This means that if use_scram_passthrough is set, some situations that might otherwise have worked are preempted, for example GSSAPI with delegated credentials. This could be enhanced in the future if there is desire for more flexibility.

Peter Eisentraut	761c79508e	postgres_fdw: SCRAM authentication pass-through This enables SCRAM authentication for postgres_fdw when connecting to a foreign server without having to store a plain-text password on user mapping options. This is done by saving the SCRAM ClientKey and ServeryKey from the client authentication and using those instead of the plain-text password for the server-side SCRAM exchange. The new foreign-server or user-mapping option "use_scram_passthrough" enables this.
