Hi ,
I am running Pgsql version 9.5.6 with :
autovacuum = on
log_autovacuum_min_duration = 0
autovacuum_naptime = 3min
I was hoping to see in errorlog all the stats time and CPU usage
for autovacumm operationfor all tables , but so far there is only one
and same table been logged , how about rest of them, the other
autovacuum param are disabled ( using the default values)
Thank you

I assume autovac not visiting those tables due to insufficient churn.
Review the docs in regards to the threshold/scale settings that
determine how aggressive autovac is.
