Hm, I kinda reversed my opinion on that, though - i.e., I no longer think that the dependency graph idea has much merit. For two reasons First, dependencies work on OIDs, not on names. Thus, for the dependency machinery to work for GUCs, they'd also need to store OIDs instead of names of referenced schema objects. (Otherwise you get into trouble if objects are renamed) Which of course doesn't work, at least for roles, because roles are shared objects, but referenced objects might be database-local. (search_path, for example). best regards, Florian Pflug -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
