I tried, but failed, because pg_database accessed in InitPostgres() before
assigning MyDatabaseId only via the function GetDatabaseTupleByOid(),
which doesn't unpack the database tuple.
Another access to a system catalog with unassigned MyDatabaseId might occur
in the has_privs_of_role() call, but pg_auth_members contains no toastable
attributes.
So for now only pg_authid is worthy of condemnation, AFAICS.

Best regards,
Alexander
