Hi there,

Using explicitly VACUUM command give me the opportunity to fine tune my 
VACUUM scheduling parameters, after I analyze the log generated by VACUUM 

On the other hand I'd like to use the auto-vacuum mechanism because of its 
facilities. Unfortunately, after I made some initial estimations for 
autovacuum_naptime, and I set the specific data into pg_autovacuum table, I 
have not a feedback from the auto-vacuum mechanism to check that it works 
well or not.  It would be nice to have some kind of log similar with the one 
generated by VACUUM VERBOSE. Is the auto-vacuum mechanism able to provide 
such a useful log ?
