It's not the costs I'm worried about so much as the side effects --- locks and so forth. Also, things like assignment of specific names for indexes and sequences seem rather problematic. In the worst case the trigger could run seeing "foo_bar_idx1" as the name of an index to be created, and then when the action actually happens, the name turns out to be "foo_bar_idx2" because someone else took the first name meanwhile. As I said, I think this suggests that you're trying to do the triggers in the wrong place. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
