That sounds nice all right, but I'm not sure it's actually helpful, because the article text is not available anywhere. I doubt most people will spend 15 bucks to buy that paper ... so we don't actually know whether the paper supports the chosen formula :-) unless you have a CACM subscription and can verify it. I think it's good to have the ACM reference anyway, for posterity, but it'd be good to (additionally) have something that people can read. -- 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
