Function returning RECORD

Hi,

I'm not be able to use a function to return the record type.

AnyBody could help me? Look this exemple:

CREATE OR REPLACE FUNCTION TESTERECORD()
RETURNS record AS '
DECLARE
vRecRetorno Record;
BEGIN
SELECT teste INTO vRecRetorno FROM (SELECT ''Function record '' AS teste) AS TABELA;
RETURN vRecRetorno;
END;
' language 'plpgsql';

CREATE OR REPLACE FUNCTION TESTECHAMARECORD()
RETURNS varchar AS '
DECLARE
vrecord RECORD;
v varchar;
BEGIN
SELECT testerecord() INTO vrecord;
v := vrecord.teste; -- Here is the error
RETURN v;
end;
' language 'plpgsql';

select testechamarecord();

When I call the testechamarecord function, the following message error appear:

record "vrecord" has no field named "teste"

Help-me, please.
