One question that just came to mind is whether Simon's no-commit-wait patch doesn't fundamentally alter the context of discussion for this. Aside from the prospect that people won't really care about group commit if they can just use the periodic-WAL-sync approach, ISTM that one way to get group commit is to just make everybody wait for the dedicated WAL writer to write their commit record. With a sufficiently short delay between write/fsync attempts in the background process, won't that net out at about the same place as a complicated group-commit patch? 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
