You only have fixed a symptom here. As a next step, the model needs to
be fixed to make the field required. That will prevent the ORM from
dropping the constraint on the inherit table.

Additionally, in the longer term, the ORM needs to be fixed to error out
in these situations, because PostgreSQL will change to prevent dropping
NOT NULL constraints on inherited tables.

I have attached a patch to fix the model, but I am not deep enough into
the ORM to fix the actual issue.
