select * from pg_catalog.pg_namespace;
just like Postgres, this must show schemas belonging to the currently selected database only

Thanks for the PR!

it just looks like there is a related CI failure in the force storage tests - could you have a look?

The below query will give a different output when opened in in-memory mode and persistence mode.

SELECT EXISTS (
	SELECT * FROM pg_catalog.pg_type t, pg_catalog.pg_namespace n
	WHERE t.typnamespace = n.oid
	AND t.typname = 'int4'
	AND n.nspname = 'main'
	);

The reason is that in this querySELECT * FROM pg_catalog.pg_type; typnamespace value is equal to

  • 0 when opened in persistence mode
  • memory-db's oid when opened in in-memory mode

So when we restrict the shcemas to return only current_database's schema as done in this PR, when typnamespace is 0 there is no system database's main schema (with oid = 0) to match any rows in the above test's join clause

You can add require noforcestorage to skip the test with force storage
