Comment:
I was able to reproduce this issue, however using geography type is really
limited on PostGIS (see
[https://docs.djangoproject.com/en/stable/ref/contrib/gis/model-api
/#geography-type-1 docs]) and `__bboverlaps` is not an option in the
general case. I wonder how we could improve this, I can imagine two
options:
- raise a system warning when `unique` is used with `geography` and skip
these fields in unique checks,
- cast `geography` fields to a `geometry` type in the query.
What do you think?
