Hello. I propose 2 features for planner:
1. Planner will estimate 2 x statistics: time of query with cache empty and with cache filled. 2. Two levels of plannig: standard and long. Long planning may be used when standard optimization generate slow plan, and may use advanced algebraic transformations: F( F(a,1), 2) = F(a, F(1,2) ) - for algebraic groups for example etc. ------------ pasman -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
