+1 to first: Aborts aren't particularly frequent actions, but having them return faster makes sense if you have a session pool and people are waiting to run another transaction. -1 to second: If there are any temporary deleted files then it is because we've done a large sort, hash join etc, so avoiding the sync makes no difference to the overall response time. -- Simon Riggs 2ndQuadrant http://www.2ndQuadrant.com ---------------------------(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
