I thought updates remain in > memory until syncpoint in pre-8.0. Am I missing somethng? The updates don't go to disk immediately (they didn't in 7.4 either). But we always allocate disk space immediately when needed, to make sure it's available. Otherwise we could face the embarrassing situation of having noplace to put rows inserted by an already-reported-committed transaction. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
