FWIW, something that bothers me is that there is 3000 random page reads... i mean, why 3000? how do you get that number as absolute for good accuracy in every relation? why not a percentage, maybe an argument to the function? also the name pgstattuple2, doesn't convince me... maybe you can use pgstattuple() if you use a second argument (percentage of the sample) to overload the function -- Jaime Casanova www.2ndQuadrant.com Professional PostgreSQL: Soporte 24x7 y capacitación Phone: +593 4 5107566 Cell: +593 987171157 -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
