value too long with postgresql

[nvbn]

When i try to create the order, i saw:

/home/nvbn/work/totemi/ENV/local/lib/python2.7/site-packages/django/db/models/fields/__init__.py:808: RuntimeWarning: DateTimeField received a naive datetime (2012-11-23 02:53:29.456187) while time zone support is active.
  RuntimeWarning)

And that:

    order.save()
  File "/home/nvbn/work/totemi/ENV/local/lib/python2.7/site-packages/plata/shop/models.py", line 172, in save
    super(Order, self).save(*args, **kwargs)

DatabaseError: value too long for type character varying(3)

What is the value of your CURRENCIES setting? And which countries are available in your shop? The country field only allows 3 characters; I mostly use django-countries, which stores only the ISO code and not the full country name.

Please reopen if you have further information about this problem. Thanks!

CURRENCIES = ('RUS',)
And it works with mysql and sqlite, but not with postgresql.

This sounds like a discrepancy between byte and character counting. Which database encoding / charset are you using?

[nvbn]

Encoding is ru_RU.UTF-8
