Hmm, what about this instead?
create table foo (
id serial primary key,
name text
);
create table bar (
foo_id integer NOT NULL REFERENCES foo ON DELETE CASCADE,
name2 text
);
create view foobar as
select f.id, f.name, b.name2 from foo f, bar b where (f.id = b.foo_id);
create rule delete_foobar as on delete to foobar do instead delete from foo
where id = OLD.id;
(works on v7.1.2)
