Hmm. I am not sure where did you read that but I don't think it has ever been stated that autovacuum is resource friendly in the default configuration (I, for one, have never tried, intended or wanted to state that). I suggest tuning the autovacuum_vacuum_cost_delay parameters if you want it to interfere less with your regular operation. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.
