Trying to do this results in:

This is on python 3.6.3rc1 with libgdal 2.2.1+dfsg-2+b2 (debian sid).
the test I'm using is:
{{{
from django.test import TestCase
from .models import Location
class RelatedGeoModelTest(TestCase):
fixtures = ['initial']
def test_17_raw_query(self):
raw = Location.objects.raw("SELECT * FROM
{}".format(Location._meta.db_table))
list(raw)
}}}
