[SQL] Function not running after upgrade 7.03 to 7.2

[juerg . rietmann]

I have three functions running under 7.03, Now, after the Upgrade to 7.2
these functions are not working.
What has changed in version 7.2 that causes this problem.

Function :

CREATE FUNCTION "buildUmfang"("bpchar") RETURNS "text" AS 'DECLARE
      list           text;
      rec          record;
BEGIN
list := '''';
FOR rec IN SELECT z_u_umfang FROM zylinder_umfang WHERE z_u_typ = $1
LOOP
      list := list || text(rec.z_u_umfang) || '','';
END LOOP;
RETURN list;
END;

' LANGUAGE 'plpgsql';
COMMENT ON FUNCTION "buildUmfang"("bpchar") IS 'Diese Funktion generiert
einen String mit allen Umfängen zum übergebenen Zylindertyp\n\n';


Query :

SELECT *,
(SELECT rtrim(buildUmfang(zylinder.z_typ), ','::text) AS rtrim) AS umfang
FROM zylinder;

Thank's in advance for any help .... jr
