django.db.utils.ProgrammingError: operator class "text_pattern_ops" does not accept data type text[]

[luminousmen]

In our development we are using django==1.8.2 and we have this strange problem on initial migrations. To be more specific the fields.py:

class LanguagesField(TextArrayField):
    def __init__(self, *args, **kwargs):
        kwargs.update({
            'verbose_name': _('языковые версии'),
            'choices': settings.LANGUAGES,
            'default': ('en',),
            'db_index': True
        })

        super(LanguagesField, self).__init__(*args, **kwargs)

    def formfield(self, **kwargs):
        kwargs['widget'] = forms.CheckboxSelectMultiple(attrs={'class': 'uioff'})
        kwargs['required'] = True

        return super(LanguagesField, self).formfield(**kwargs)

In models.py:

langs = LanguagesField()

The initial migration:

fields = [
...

('langs', multilanguages.fields.LanguagesField(default=('en',), choices=[(b'en', '\u0410\u043d\u0433\u043b\u0438\u0439\u0441\u043a\u0438\u0439'), (b'ru', '\u0420\u0443\u0441\u0441\u043a\u0438\u0439'), (b'tr', '\u0422\u0443\u0440\u0435\u0446\u043a\u0438\u0439')], dbtype='text', verbose_name='\u044f\u0437\u044b\u043a\u043e\u0432\u044b\u0435 \u0432\u0435\u0440\u0441\u0438\u0438', db_index=True)),
...
]

And error on ./manage.py migrate
