Passing a ROWTYPE to a function

I'm trying to write a function that takes a %ROWTYPE as an argument.
I'm just not sure how to call it from another function.

This is what I tried:

<fixed><fontfamily><param>Courier New</param>CREATE TABLE t1 (x int, y
int);

INSERT INTO t1 VALUES (1, 2);

CREATE OR REPLACE FUNCTION g1(t1) RETURNS int LANGUAGE plpgsql AS '

BEGIN

    RETURN $1.y;

END';


CREATE OR REPLACE FUNCTION g2(int) RETURNS int LANGUAGE plpgsql AS '

DECLARE item t1%ROWTYPE;

BEGIN

    SELECT INTO item * FROM t1 WHERE x = $1;

    RETURN g1(item);

END';


SELECT g2(1);

</fontfamily></fixed>

This is what I got:

<fixed><fontfamily><param>Courier New</param>CREATE TABLE

INSERT 28089 1

CREATE FUNCTION

CREATE FUNCTION

psql:/tmp/test.sql:16: ERROR:  column "item" does not exist

CONTEXT:  PL/pgSQL function "g2" line 4 at return

</fontfamily></fixed>


I'm using posgresql 7.4.6.


Thanks.
