[HACKERS] Does setof record in plpgsql work well in 7.3?

[Masaru Sugawara]

Hi, all

Does 7.3 support "SETOF RECORD" in plpgsql ?
As far as I test it, a function using it in plpgsql always seems to return
no row. On the other hand,  a sql function returns correct rows.  

If 7.3 doesn't support it in plpgsql, I would think plpgsql needs to raise
an error rather than return "0 rows" message. Am I misunderstanding
how to use? 


------------------------------------------------------
CREATE TABLE test (a integer, b text);
INSERT INTO test VALUES(1, 'function1');
INSERT INTO test VALUES(2, 'function2');
INSERT INTO test VALUES(1, 'function11');
INSERT INTO test VALUES(2, 'function22');


CREATE OR REPLACE FUNCTION myfunc(integer) RETURNS SETOF record AS '
  DECLARE
     rec record;
  BEGIN
     FOR rec IN SELECT * FROM test WHERE a = $1 LOOP
         RAISE NOTICE ''a = %, b = %'',rec.a, rec.b;
     END LOOP; 
     RETURN rec;
  END;
' LANGUAGE 'plpgsql';

SELECT * FROM myfunc(1) AS t(a integer, b text);

NOTICE:  a = 1, b = function1
NOTICE:  a = 1, b = function11
 a | b 
---+---
(0 rows)



CREATE OR REPLACE FUNCTION myfunc(integer) RETURNS SETOF record AS '
    SELECT * FROM test WHERE a = $1;
' LANGUAGE 'sql';

SELECT * FROM myfunc(1) AS t(a integer, b text);

 a |     b      
---+------------
 1 | function1
 1 | function11
(2 rows)
