Function works in 8.4 but not in 9.0 beta2 "ERROR: structure of query does not match function result type"

Hi
I've started testing our applications against PostgreSQL 9.0 beta2 and found
that this function now does not work anymore(rewritten to be as small and
anonymous as possible)
CREATE TYPE test_type AS(
product text,
amount numeric(30,4)
);
CREATE FUNCTION test_func() RETURNS SETOF test_type AS $$
BEGIN
RETURN QUERY SELECT 'test'::text, 30.2::numeric;
END;
$$ LANGUAGE plpgsql STABLE;
Output in postgresql 8.4:
postgres=# SELECT version();
version

You need to actually coerce the 30.2 to numeric(30,4), not just numeric.
The former behavior wasn't self-consistent.

The 9.0 release notes are not really up to snuff yet :-(. The only
thing in the notes about it is "Allow PL/pgSQL to handle row types with
dropped columns" which is a rather inadequate description of the
consequences of that patch. We're probably going to need to call it out
as an incompatibility.

I was suspecting that it was incompatibility that hadn't been documented correctly, just wanted to make sure that this was the case. It probably should go into the release notes too since it is bound to affect others....
