Far as I know, we were OK on that before.

test=# create table a(f1 int, f2 int);
CREATE
test=# create table b(f1 int, f3 int);
CREATE
test=# select * from a natural join b;
 f1 | f2 | f3
----+----+----
(0 rows)

test=# select * from a join b using(f1);
 f1 | f2 | f3
----+----+----
(0 rows)

test=# select * from a join b on (a.f1=b.f1);
 f1 | f2 | f1 | f3
----+----+----+----
(0 rows)

This is per spec, no?
