I don't really think this is worth worrying about. A sub-one-percent regression on a highly artificial test case doesn't seem like a big deal. Anybody less determined than you would have been unable to measure that there even is a regression in the first place, and that's basically everyone. -- Robert Haas EDB: http://www.enterprisedb.com
