Hello

        I know so I need to use column definition list when I have SRF 
function without def of own type. But I don't understand why. In my SRF 
function I specify all informations about columns?

  TupleDescInitEntry (tupdesc, 1, "idn", INT4OID, -1, 0, false);
  TupleDescInitEntry (tupdesc, 2, "idv", VARCHAROID, -1, 0, false);

Why I have to duplicate to?

Thank You
Pavel Stehule
