Doh! I was looking at last_vacuum. Unfortunately, the *last_autovaccum*
column is completely blank on the tables I'm inserting into, so I guess
it's never worked there.
But I do see the stats collector running, and upping the log level to
debug2 does show that the autovacuum at least starts running, and never
seems to have any errors.
.....hmmmm......
After some tests, it seems that autovacuum doesn't kick in from simple
inserts, as the manual says it will. You have to delete and/or update as
well. Am I misreading the manual?
