I am now much more concerned with the delay, and am wondering if I should start thinking about trying my idea of looking for near-committers and post the patch to the list to see if anyone likes it for 7.1 final. Vadim will not be back in enough time to write any new code in this area, I am afraid. We could look to fix this in 7.1.1. Let's see what the pgbench tester comes back with when he sets the delay to zero. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
