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?
