In PostgreSql 8.1 i've tried to use Out parameter but when I've changed
function (added Out parameter)

------------------------------------

CREATE OR REPLACE FUNCTION reffunc3(FROM_ID in integer,COUNT_ROW OUT
integer) RETURNS SETOF Person AS '
DECLARE
rec RECORD;
BEGIN

SELECT count(*) INTO COUNT_ROW FROM Person WHERE ssn>FROM_ID ;

FOR rec IN SELECT ssn,name FROM Person WHERE ssn>FROM_ID
LOOP
c;RETURN NEXT rec ;
END LOOP ;

RETURN ;
END;
' LANGUAGE plpgsql;



--SELECT * from reffunc3(1) ;
----------------------------------------

i've seen :

----
ERROR: function result type must be integer because of OUT parameters
----

Of course when I change parameter to Integer it must be Record error
appears.

What should I change, and how to call this function?
