DROP TABLE... CASCADE weirdness

Hackers,

Suppose I do

CREATE TABLE a (a int);
CREATE TABLE b () INHERITS (a);

And then I want to drop both tables:

regression=# DROP TABLE a, b;
NOTICE:  table b depends on table a
ERROR:  Cannot drop table a because other objects depend on it       Use DROP ...  CASCADE to drop the dependent
objectstoo
 


Oh, so I use CASCADE:

regression=# DROP TABLE a, b CASCADE;
NOTICE:  Drop cascades to table b
ERROR:  table "b" does not exist

I understand what's going on and how to get the desired behavior, but
it's weird and I think it should be fixed if possible.
