What sort of application are you envisioning? If you mean there are applications for which avoiding duplicate notifications is a performance win, I think those applications are on shakey ground: the LISTEN/NOTIFY interface doesn't guarantee that no duplicate notifications will be delivered (it merely doesn't guarantee they *will* be delivered). Personally, I think delivering all notifications by default is simpler behavior for the application programmer to understand. If you want to avoid doing work for duplicate notifications, you realistically need to implement that yourself anyway. -Neil ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
