No we only do a "vacuum analyze" when we do something manually.
Otherwise, it's all "autovacuum". Never done a "vacuum full" --
should we do one now given that we've overrun our max_fsm_pages?

Nope, there's no line that includes such useful info. The entire
verbose output was included in my note. I did not see the words
"Current limits are". Do I need to enable something in the conf file
to get more verbose output? "debug2", "debug3" -- kind of stuff?
