True. In fact this brings up a problem of using the xid for recovery stop. The interesting point is that you might recover to just before xact 123, but that doesn't mean you get xact 122. Still I think we need to add xid to the log_line_prefix for PITR and make it clear that specifying a recovery xid doesn't always include earlier xids. I have added this to the open items list. -- Bruce Momjian | http://candle.pha.pa.us [EMAIL PROTECTED] | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
