At that time, I didn't start questioning your sanity. In fact we all applauded that because it was a great performance gain. The fact that you disagree with me does not make me insane. Inaction on this point, resulting in a year's delay, will be considered to be a gross waste by the majority of objective observers. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
