While working on adding PostGIS support to the django-multitenant library
I had some issues with the features_class that was overridden in the
DatabaseWrapper subclass. After some troubleshooting I was able to
determine this is because the PostGIS backend explicitly sets the
`features`, `ops`, and `introspection` properties to the file local
classes:
https://github.com/django/django/blob/stable/4.2.x/django/contrib/gis/db/backends/postgis/base.py#L91
I was able to work around this behaviour by overriding the constructor and
setting the features property explicitly:
https://github.com/citusdata/django-multitenant/pull/150/files#diff-
0d077af5d4e86f31f478785458ea6a03768a15aea077f49b9a79ffca8b0fe4beR37
This isn't very intuitive as other database backends will respect setting
the `_class` properties to instantiate classes.
