So, I have checked my log and I see an autovacuum running once every minute
on our various databases being hosted on the server - once every minute!

From what I can see, autovacuum is hitting the db's in question about once
every five minutes. Does this imply an ANALYZE is being done automatically
that would meet the requirements we are talking about here? Is there any
benefit ot explicitly performing an ANALYZE?

(Or does this go hand-in-and with turning off autovacuum...?)
