Why is this wrong ?:

DROP SCHEMA test CASCADE ;
CREATE SCHEMA test;

CREATE TABLE test.parent (
	id serial PRIMARY KEY,
	opis text 
);

CREATE TABLE test.child_data (
	id serial PRIMARY KEY,
	id_parent int ,
	podaci text,
	FOREIGN KEY (id_parent) REFERENCES test.parent(id)
);

CREATE VIEW test.child AS 
	SELECT 	p.id AS id,
			p.opis AS opis,
			c.id AS id_data,
			c.id_parent AS id_parent,
			c.podaci AS podaci 
	FROM
	test.parent p, test.child_data c 
	WHERE c.id_parent = p.id;
 
CREATE FUNCTION test.testfi(test.child) RETURNS bool AS '
DECLARE
	_NEW ALIAS FOR \$1;
BEGIN
	RAISE NOTICE ''%'',_NEW.opis;
	INSERT INTO test.parent (id,opis) VALUES (_NEW.id,_NEW.opis);
	INSERT INTO test.child_data (id,id_parent,podaci) VALUES 
(_NEW.id_data,_NEW.id,_NEW.podaci);
	RETURN TRUE;
END; ' 
LANGUAGE 'plpgsql';

CREATE RULE child_ins AS ON INSERT TO test.child
DO INSTEAD SELECT test.testfi(NEW);


INSERT INTO test.child(id,id_data,opis,podaci) VALUES (1,1,'Opis','podaci');


Gives:
	(-403)ERROR:  cannot handle whole-row reference

Can I pass NEW & OLD from rule into function in any way ?
Any suggestions ?

Regards !

It works in CVS tip ;-).  No chance in 7.4 or earlier, however.
You'll have to pass the components of the row as separate arguments
to the function.
