I'm using 8.4.1 I want to add a column to a table, but there are update triggers that will fire that don't need to fire for this operation. So, I'd like to add the column with triggers off. Normally this operation would take 10 or so seconds, so locking the table for that amount of time is not a big deal. I just want to make sure that no new data gets written to the table while the triggers are disabled. BEGIN; ALTER TABLE foo ADD COLUMN bar DISABLE TRIGGER USER; COMMIT; seems to leave the triggers disabled. My tests seem to show that BEGIN; ALTER TABLE foo DISABLE TRIGGER USER; locks the table fully, then ALTER TABLE foo ADD COLUMN bar; ALTER TABLE foo ENABLE TRIGGER USER; COMMIT; gets the job done. I only pause because I figured that the single DISABLE triggerin transaction would have flopped back when the transaction committed. I was wrong about that.... I only need a little bit of affirmation or a kick in the right direction.
