While working on a patch for #18094 I stumbled on this issue.
{{{
>>> from django.contrib.auth.models import User
>>> from django.db import models
>>> def user_post_delete(sender, instance, **kwargs):
... print "User post delete sent"
...
>>> User.objects.create().delete()
User post delete sent
>>> u = User.objects.create()
>>> User.objects.only('id').get(pk=u.pk).delete()
}}}
The patch should be a simple check for ``_deferred``
[https://code.djangoproject.com/browser/django/trunk/django/db/models/deletion.py#L155
here].
