Yeah. Any kind of bulk load into an empty table can be a problem, even if it's not temporary. When you load a bunch of data and then immediately plan a query against it, autoanalyze hasn't had a chance to do its thing yet, so sometimes you get a lousy plan.
May be introducing something like 'AutoAnalyze' threshold will help? I mean that any insert/update/delete statement that changes more then x% of table (and no less then y records) must do analyze right after it was finished.
Defaults like x=50 y=10000 should be quite good as for me. Best regards, Vitalii Tymchyshyn -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
