Well the first thing to do is increase the verbosity of the
pg_autovacuum logging output.  If you use -d2 or higher, pg_autovacuum
will print out a lot of detail on what it thinks the thresholds are and
why it is or isn't performing vacuums and analyzes.   Attach some of the
log and I'll take a look at it.
