Thread: disabling triggers?
Hi, I've noticed the recent query about dropping a function with a trigger. I've got a trigger/function pair that I need to disable while I do a manual update. Is it safe to drop the trigger, then re-create it on its own, or should I do the trigger/function pair. Is there a better method of temporarily disabling a trigger?

Dropping the function has at least one big disadvantage: if the same function is supporting similar triggers on other tables, dropping the function would break those triggers. > Is there a better method of temporarily disabling a trigger? You could reach in and hack the reltriggers field in pg_class, but dropping and recreating the trigger seems a lot cleaner and safer. regards, tom lane
