Error working with Temporary Sequences in plpgsql in 8.1 (8.0 works fine)

Hi,

here is a testcase:

CREATE OR REPLACE FUNCTION testseq() RETURNS void AS
$BODY$
BEGINCREATE TEMP SEQUENCE test;PERFORM testseq1();DROP SEQUENCE test;RETURN;
END; $BODY$ LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION testseq() OWNER TO postgres;


CREATE OR REPLACE FUNCTION testseq1() RETURNS void AS
$BODY$
DECLARE I INTEGER;
BEGINI:= nextval('test');RETURN;
END; $BODY$ LANGUAGE 'plpgsql' VOLATILE;
ALTER FUNCTION testseq1() OWNER TO postgres;


SELECT testseq();

-- this works fine.

SELECT testseq();


ERROR:  could not open relation with OID 21152
CONTEXT:  PL/pgSQL function "testseq1" line 3 at assignment
SQL statement "SELECT  testseq1()"
PL/pgSQL function "testseq" line 3 at perform



Greetings,

Daniel.
