I remember the other difference between 8.0 and pre-8.0. When a backend has to write a block in 8.0, it does a write _plus_ fsync(), while in pre-8.0 it did only a write. There was a proposal to pass backend write information to the background writer so it would know to fsync at checkpoint, but it was decided that backend writing would be rare. I think we have to rethink that assumption. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (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 7: don't forget to increase your free space map settings
