It's important that the stats target get increased as well, it looks like you're not getting enough buckets to get a good estimate of rows to be returned for various conditions. # show default_statistics_target ; default_statistics_target --------------------------- 10 # alter database smarlowe set default_statistics_target=200; ALTER DATABASE # analyze; Then run the explain analyze again and see if your row estimates are closer and if the plan changes. -- Sent via pgsql-sql mailing list (pgsql-sql@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-sql
