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?
Thanks a lot for your help...
