[https://github.com/django/django/blob/master/django/contrib/postgres/forms/array.py
django.contrib.postgres.forms.array] uses several times the old
`Exception.message` attribute to get the error message instead of
`str(Exception)`. This breaks compatibility with Python 3 at least when
using `SplitArrayField`, but it should also lead to errors on other form
fields from this module.
Minimal example:
{{{#!python
from django.contrib.postgres.forms import SplitArrayField
from django.forms import IntegerField
SplitArrayField(IntegerField(max_value=100), size=2).clean([0, 101])
}}}
This leads to an `AttributeError: 'ValidationError' object has no
attribute 'message'`
