title: Django-tenant-schemas and GeoDjango together
body: <p>I want to use <a href="http://django-tenant-schemas.readthedocs.io/en/latest/install.html" rel="nofollow noreferrer">django-tenant-schemas</a> and <a href="https://docs.djangoproject.com/en/1.11/ref/contrib/gis/tutorial/" rel="nofollow noreferrer">GeoDjango (PostGIS)</a> in my Django project. I have a single default database. But both django-tenant-schemas and GeoDjango want me to set a custom Engine for the Database in the settings.</p>
  
  <p>django-tenant-schemas want it to be set to <code>tenant_schemas.postgresql_backend</code> <br>
  while GeoDjango wants it to be set to <code>django.contrib.gis.db.backends.postgis</code>. </p>
  
  <p>Is there any workaround to this issue? </p>
  
  <p><em>Edit:</em> I want to use GeoDjango for a single model only and I am using a single Postgres database.</p>
