No. > If so, we can put this assertion in. Only if you want it to crash every so often. The "race condition" is that a signal delivered right about the time the check is made may be serviced before the event is set, meaning that after the dust settles the event will still be set when there's nothing to do. This was true before, too, and will have no impact worse than causing an extra entry to dispatch_signals later on. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
