Hi,<br /><br /> We are testing PostGreSQL 8.3 RC2 on our beta plateform and we are facing some problems with plpgsql
function.<br/><br /> Here's a failing test case, which worked well on postgresql 8.1 :<br /><br /><pre>
 
Create this function :

CREATE OR REPLACE FUNCTION test(param integer)
  RETURNS text AS
$BODY$DECLARE
       attribute TEXT:='';
       query TEXT;
       curs REFCURSOR;
       rec RECORD;
BEGIN 
if (param=1) THENquery := 'SELECT ''test''::varchar AS label';ELSE query := 'SELECT ''test''::text AS label';END IF;
RAISE NOTICE '%',query;
OPEN curs for EXECUTE query;
FETCH curs into rec;
attribute=rec.label;
CLOSE curs;

RETURN attribute;
END;$BODY$
  LANGUAGE 'plpgsql' VOLATILE

Execute this function, and this sql :

postgres=# SELECT test(1);
NOTICE:  SELECT 'test'::varchar AS labeltest 
------test
(1 ligne)

and now :
postgres=# SELECT test(2);
NOTICE:  SELECT 'test'::text AS label
ERROR:  type of "rec.label" does not match that when preparing the plan
CONTEXT:  PL/pgSQL function "test" line 15 at assignment


It seems that if the type of "label" changes from varchar to text it crashes...

Thanks for fixing this!
