In a vanilla project and app (all default settings, nothing changed),
trying to create a model record with a CharField longer than what is
defined, works (no exception raised, no truncation):

{{{
# models.py
from django.db import models

class Foo(models.Model):
name = models.CharField(max_length=5)
}}}

{{{
$ python manage.py shell
>>> from foo.models import Foo
>>> Foo.objects.create(name='abcdefghijk')
<Foo: Foo object (1)>
>>> f = Foo.objects.first()
>>> f
<Foo: Foo object (1)>
>>> f.name
'abcdefghijk'
}}}

Maybe I am missing something, or maybe that's just sqlite behavior, but
shouldn't some exception be raised?
