I also agree that if we provide pg_table_size, the issue of "pg_relation_size doesn't do what I want" goes away without needing to even change the existing documentation--people don't come to that section looking for "relation", they're looking for "table". Bernd, there's a basic spec if you have time to work on this. -- Greg Smith 2ndQuadrant Baltimore, MD PostgreSQL Training, Services and Support greg@2ndQuadrant.com www.2ndQuadrant.com
