With so many questions coming to this forum that are due to insufficient statistics, why not just increase the default_statistics_target? I assume there is a down side, but I've never seen it discussed. Does it increase planning time? Analyze time? Take lots of space? Yes, yes, and yes. We already did crank up the default default_statistics_target once (in 8.4), so I'm hesitant to do it again. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
