This should would a little better.

select
        distinct on (titolo)
                     ^^^^^^
        'any' as cod_rif,
        titolo,
        (
         select A1.sum(quantity) from test_t as A1
         where A1.titolo = test_t.titolo
        ) as sum_qty,
        cmf,
        u_qq,
        mont,
        vend,
from
        test_t
group by
        titolo,
        sum_qty,
        cmf,
        u_qq,
        mont,
        vend
;
