This is not a bug. LIKE says the column isn't inherited, so it exists
in the child independently of whether it exists in the parent.
Or, if you want to add it up: the child starts out with one local
definition of the column (from LIKE) and one inherited (from INHERITS).
Dropping the column from the parent removes the latter, but you still
have the former, so the column stays.

Just out of curiosity, is there any actual use-case for such a silly
thing?
