Comment:

 This looks to be a DB level inconsistency, not something Django can
 control.  Unless there's something I'm missing closing as wontfix.

 Given the following models:
 {{{
 #!python
 from django.db import models

 class A(models.Model):
 name = models.CharField(max_length=50)

 class B(A):
pass

 class C(A):
pass
 }}}

 The following query returns different queryset order for `sqlite3` vs.
 `postgresql_psycopg2`:
 {{{
 #!python
 A.objects.order_by('b', 'name')
 }}}

 SQLite will sort B objects, followed by C objects. PostgreSQL will sort C
 objects, followed by B objects.
