AFAICS, the only way in which current autovac treats !datallowconn
databases specially is this test in do_autovacuum:
if (dbForm->datistemplate || !dbForm->datallowconn)    default_freeze_min_age = 0;else    default_freeze_min_age =
vacuum_freeze_min_age;

Perhaps there's something wrong with the idea of setting freeze_min_age
to zero?
