Schema.Table.Col resolution seems broken in Alpha5

Hackers,

It appears that something broke the ability to refer to columns by full
SQL path names in 9.0. That is, references to columns as
schema.table.col will produce a completely bogus error which did not
exist on previous versions.

The following works perfectly well in 8.4:

postgres=# create table test1( id serial, val integer );
NOTICE: CREATE TABLE will create implicit sequence "test1_id_seq" for
serial column "test1.id"
CREATE TABLE
postgres=# create table test2( id serial, val integer );
NOTICE: CREATE TABLE will create implicit sequence "test2_id_seq" for
serial column "test2.id"
CREATE TABLE
postgres=# insert into test1(val) select gs.i from generate_series(1,10)
as gs(i);
INSERT 0 10
postgres=# insert into test2(val) select gs.i from generate_series(1,10)
as gs(i);
INSERT 0 10
postgres=# select test1.* from public.test1, public.test2 where
public.test1.id = public.test2.id;
id | val
----+-----
1 | 1
2 | 2
3 | 3
4 | 4
5 | 5
6 | 6
7 | 7
8 | 8
9 | 9
10 | 10
(10 rows)

postgres=# update public.test1 set val=public.test2.val from
public.test2 where public.test1.id = public.test2.id;
UPDATE 10

However, it breaks in 9.0a5:

postgres=# create table test1( id serial, val integer );
NOTICE: CREATE TABLE will create implicit sequence "test1_id_seq" for
serial column "test1.id"
CREATE TABLE
postgres=# create table test2( id serial, val integer );
NOTICE: CREATE TABLE will create implicit sequence "test2_id_seq" for
serial column "test2.id"
CREATE TABLE
postgres=# insert into test1(val) select gs.i from generate_series(1,10)
as gs(i);
INSERT 0 10
postgres=# insert into test2(val) select gs.i from generate_series(1,10)
as gs(i);
INSERT 0 10
postgres=# select test1.* from public.test1, public.test2 where
public.test1.id = public.test2.id;
ERROR: invalid reference to FROM-clause entry for table "test1"
