I start with:

autovacuum = on # Enable autovacuum subprocess? 'on'
# requires track_counts to also be on.
log_autovacuum_min_duration = 0 # -1 disables, 0 logs all
autovacuum_max_workers = 3 # max number of autovacuum subprocesses
autovacuum_naptime = 60min # time between autovacuum runs

Then stop/start postmaster...

It's now 19:06 and no autovacuum; why not?
