It's important to have a sense of proportion about the problem. The worst thing that a collision can do is lead the DBA on a bit of a wild goose chase. Importantly, collisions across databases and users are impossible. I've always taken the view that aggregating query statistics is a lossy process, and these kinds of problems seem like a more than acceptable price to pay for low-overhead dynamic query statistics . -- Peter Geoghegan http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
