Обсуждение: inheritance and foreign keys

Do inheritance and foreign keys work together?  I can't seem to get
them to.

Specifically, I want to create a table A which has sub-tables A*, and
I want to create a table B which references the primary key from A*,
not from A.

Is this possible?

Not currently.  The foreign key code isn't terribly bright about
inheritance trees, and some of the supporting code isn't there yet
(inherited primary keys).
