* stage: Unreviewed => Accepted
* summary:
Composite primary key creates invalid migration when one of its fields
is inherited
=> Composite primary key wrongly allows non-local fields to be
referenced

Comment:

The crux of the issue here is that `CompositePrimaryKey` allows non-local
field to be referenced. Fields inherited from an abstract based should be
allowed to be referenced but ones from a concrete base (aka non-local /
defined on a referenced table) should not.
