I think that's the right way, only that I wouldn't call FSMVacuum() inside the loop but only once you're out of it. FWIW I had to add a FSMVacuum call somewhere in the BRIN code also, which I didn't like at all. If there's a way to optimize this "bubbling up" of some individual page all the way to the root level, that would probably be a lot better than what it's currently doing. -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
