We didn't, but while I agree with the idea, I think 5% is too low. I don't want autovacuum to get excessively aggressive. Is 10% not enough? How about the analyze scale factor, should we keep the current 10%? I have less of a problem with reducing it further since analyze is cheaper than vacuum. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
