Comment:

 The list of operations generated should look like:

 1. Alter the field Bazz.bar type to an IntegerField in order to drop the
 FK constraint.
 2. Perform the Bar.bar_id rename to external_id;
 3. Alter back the field Bazz.bar to a FK referring to Bar.external_id;

 @snopoke, can you confirm these operations work?
