Foreign keys don't inherit to children table on either
the fk or pk side. Note also that the primary keys in
the above will not guarantee that sigle is unique
across the whole set, only across each table individually.

Pretty much the only workaround I know of is to make a table
with the key columns and have each of the tables in the
inheritance tree have its key columns reference that and anything
that wants to reference the inheritance tree references
the other table instead.
