Well, I will ask a little more clear: 1. A function could be declare to return a RECORD value? (the manual doesn't put it so clear, mention only simple return values and declaration values, not return values). 2. It will be better declare that function as a parametrized view or as a pgsql function? 3. If the record value is not a right return value, what kind of return value could I use for it?
