postgresql_psycopg2 blows up when you try to create a cursor with postgresql 8.3.1 on windows

[grand@…]

On windows, configured to work with postgresql 8.3.1 creating a cursor blows up due to the format of the postgresql version string.

>>> from django.db import connection
>>> cursor = connection.cursor()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "C:\python25\lib\site-packages\django\db\backends\postgresql_psycopg2\base.py", line 57, in cursor
    postgres_version = [int(val) for val in cursor.fetchone()[0].split()[1].split('.')]
ValueError: invalid literal for int() with base 10: '1,'

The version string returned by postgresql was 'PostgreSQL 8.3.1, compiled by Visual C++ build 1400'
It is choking on the comma after the version number. Here is a modified base.py line 57 that fixes the problem:

            postgres_version = [int(val) for val in cursor.fetchone()[0].split()[1].replace(',','').split('.')]

This is fixed in trunk r7415.
