What's your point? Those stats are correct for the current process (or if not, better take it up with your kernel vendor) and we've never stated that they are anything else than process-local stats. In every version of Postgres it's been possible that pages dirtied by one process are actually written by some other process --- the bgwriter isn't doing anything except altering the probabilities a bit. regards, tom lane ---------------------------(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
