Comment:
I just ran into this issue. I am trying to return unique Session keys from
a table. I tried
PageRequest.objects.order_by('session').distinct().count() and I get 217
records and not 1 that I should be getting. Would be nice to just be able
to do PageRequest.objects.all().distinct('session').count()
Looking forward to your new patch Manfred Wassmann. Thanks for the great
work!
