Hi all -- I just upgraded one of my projects to Django 1.8 from 1.7.7 and 
in a view function where we're doing manual transaction management 
(Postgres) I'm now getting the error in the subject line.

Basic gist of the code involved:

def foo(request):
  try:
    transaction.set_autocommit(False)

    ... do stuff involving multiple database actions ...
  except (DatabaseError, Exception) as e:
    transaction.rollback()

This worked fine in 1.7.7 so I'm not sure what I need to change to get it 
working with 1.8.

I did read the docs on the atomic() functionality and took a few runs at 
that but just wound up with different errors, so I thought I'd start with 
what I originally had and see what I need to change to make Django 1.8 
happy. But if using the atomic() stuff is preferable any tips around that 
would also be appreciated; I can post the errors I'm getting when trying 
things that way as needed.

Appreciate any ideas anyone has. Thanks.
