A probably serious and maybe not entirely obvious problem with this is that it would increase the amount of statistical information we keep by a pretty large multiple. How many columns do you have in a typical table? 20-30? That's a lot of data for a statistics collector that, regrettably, is already overloaded. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
