Should date - date return type integer, not interval?

/* ahammond@test:5432/test =# */ SELECT ('2005-03-04'::timestamp -
'2005-01-01'::date)::interval;
~ interval
- ----------
~ 62 days
(1 row)

/* ahammond@test:5432/test =# */ SELECT ('2005-03-04'::date -
'2005-01-01'::date)::interval;
ERROR:  cannot cast type integer to interval
