Consider the following models:
{{{
from django.db import models
class Father(models.Model):
name = models.CharField(max_length=200)
class Son(Father):
class Meta:
ordering = ("name",)
}}}
Then, the following query:
{{{
Son.objects.filter(pk__in=Son.objects.all().distinct()[:10])
}}}
results in an invalid SQL query. SQLite complains with "only a single
result allowed for a SELECT that is part of an expression".
