If we assume that we want the results accurate to within 5%, then we can work out a good sampling rate to achieve that accuracy. We would probably need a counting mechanism that didn't slow down O(N) as our allocations get bigger. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
