 An SQL-error is raised when updating a queryset which includes an
 annotation created using a subquery, which in turn also uses an


 class Recursive(models.Model):
     name = models.CharField(max_length=10)
     link = models.IntegerField()
     parent = models.ForeignKey('self', models.CASCADE, null=True)

 rec1 = Recursive.objects.create(name="r1", link=1)
 rec2 = Recursive.objects.create(name="r2", link=1)
 rec3 = Recursive.objects.create(name="r11", parent=rec1, link=2)

 latest_parent =

 Recursive.objects.filter(parent__isnull=False) \
         .annotate(parent_link=F('parent__link')) \
         .annotate(p=Subquery(latest_parent.values('pk')[:1])) \
