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.
