Stephen, I am using Django 1.9.5, PostgreSQL 9.3
I do not know, maybe the order of the apps may be interfering in the way
Django sorts the commands to be sent to the postgresql.
INSTALLED_APPS = [
'core', # here: Account, Log
'myapp', # here: Car, CarLog
What is happening is that post_delete is trying to create a log for an
account that does not exist. The exception doesn't works.
This seems to be a bug.
