A few other random thoughts on this document: 1. The section on default_statistics_target needs some updating - the default is 100 in 8.4+. 2. Reading the section on checkpoint_segments reminds me, again, that the current value seems extremely conservative on modern hardware. It's quite easy to hit this when doing large bulk data loads or even a big ol' CTAS. I think we should consider raising this for 9.1. I don't have a real strong opinion on what we should raise it TO - I think it's basically a question of how much temporary disk storage we think we can use during a large bulk data load without having users come back and say "wtf?" - but it seems to me that we're not doing ourselves any favors by having this set to a value where the first advice we give our users is "try tripling it". ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
