Description:        Error "relation with OID ... does not exist" when using
temporary table in function.
Details: 

After running function proc_3 (described below) more than once error
"relation with OID ... does not exist" occures. 

First run of function proc_3() is OK but the second run always fails until
we recreate function proc_2(). 

Script to reproduce.

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

--DROP FUNCTION proc_1();

CREATE OR REPLACE FUNCTION proc_1() RETURNS int AS
$BODY$
DECLARE 
        __nCount int;
BEGIN
        SELECT INTO __nCount COUNT(*) FROM __tmp_xx;
        return __nCount;
END;
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;


--DROP FUNCTION proc_2();

CREATE OR REPLACE FUNCTION proc_2() RETURNS int AS
$BODY$
DECLARE 
        __nCount int;
BEGIN
        CREATE TEMPORARY TABLE __tmp_xx(
                nId int PRIMARY KEY,
                wstrName varchar(256) NOT NULL
        );
        INSERT INTO __tmp_xx (nId, wstrName) VALUES (1, 'xx');
        __nCount := proc_1();
        DROP TABLE __tmp_xx;
        return __nCount;
END
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;


--DROP FUNCTION proc_3();

CREATE OR REPLACE FUNCTION proc_3() RETURNS int AS
$BODY$
DECLARE 
        __nCount int;
BEGIN
        __nCount = proc_2();
        --DELETE FROM t_res;
        --INSERT INTO t_res(nId, nValue) VALUES(1, __nCount);
        return __nCount;
END
$BODY$
  LANGUAGE 'plpgsql' VOLATILE;


SELECT * FROM proc_3();
