[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'`
