Aside from the issues pointed by Kyotaro-san in his review, I still haven't made my mind about whether to base the use statistics targets set for the attributes.

I wonder what Dean's opinion on this is, as he added the current logic. regards -- Tomas Vondra http://www.2ndQuadrant.com PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
