I'm also now more than just slightly skeptical about whether pg_database should have a toast table. Has anybody tried, say, storing a daticurules field wide enough to end up out-of-line?
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
