"BEFORE INSERT" was the problem here, "AFTER INSERT" works fine
Thanks for all answers.

The question becomes how do you update the "item id" on the "groups"
table when you add new records to "items".
I have a trigger on items table:
CREATE TRIGGER items_insert
BEFORE INSERT
ON items
FOR EACH ROW
EXECUTE PROCEDURE items_oninsert();
CREATE OR REPLACE FUNCTION items_oninsert()
RETURNS trigger AS
$BODY$
BEGIN
UPDATE groups SET last_item = NEW.id WHERE id=NEW.group AND
(last_item IS NULL OR last_item<NEW.id);
RETURN NEW;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE;
Thanks!
