There is a very simple answer to this, which I think I suggested to Joe originally, but it's not in the code now: the initial calculation of finish_time = now() + timeout must add one. This ensures that any roundoff error is in the conservative direction of timing out later, rather than sooner. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
