It's something that we probably should fix on the server side. IIRC the thing that was unresolved when we last discussed this was what time now() should reflect --- when you issue BEGIN, or when things really start to happen? To make the change fully transparent we'd have to define now() as "when you issued BEGIN", but there's a pretty good argument that now() should correspond to the time of the transaction snapshot. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
