'') RETURNING "model_inheritance_place"."id"

The values are empty strings in the query 1, So I don't think this gives
the expected results. The name and address should have their respective
values instead of empty strings.

defined in the first place since place_ptr conflicts.
Along with the field {{{place_ptr}}} , the following fields, i.e all the
fields of {{{Place}}} model seems to be
{{{<django.db.models.fields.AutoField: id>,
<django.db.models.fields.CharField: name>,
<django.db.models.fields.CharField: address>}}} present twice without any
conflicts or errors. So I think it would make sense if we disallow the
case-4 according to comment:8
