26120	Make HStoreField cast its key/values to strings	Przemek	Greg Chapple	"Suppose I have a simple model:

{{{
class Simple(models.Model):
    data = HStoreField(default={})
}}}

I can save hstore with mixed types, which is normal:

{{{
    simple = Simple.objects.create(data = {'a': 1, 'b': 'B'})
}}}

But the `update` function throws an exception:

{{{
   Simple.objects.filter(id=simple.id).update(data={'a': 1, 'b': 'B'})
}}}
