New description:
If I pickle queryset.query which is GIS model I get following results
(using Oracle as database):
qs = MyModel.objects.filter(id=12345)
before pickling:
{{{
>>> qs.query
<django.contrib.gis.db.models.sql.query.GeoQuery object at 0x0199FB90>
>>> qry_str = pickle.dumps(qs.query)
>>> qry = pickle.loads(qry_str)
>>> qry
<django.db.backends.oracle.query.OracleQuery object at 0x019C3F70>
}}}
Somehow query object has changed. It works as expected on non GIS models.
