postgresql8.3 on window "select version()" format

[anonymous]

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: '3,'

because "select version()" returns:

testdb=# select version();
                       version
-----------------------------------------------------
 PostgreSQL 8.3.3, compiled by Visual C++ build 1400
(1 row)

i think the best way is use PQparameterStatus() or PQserverVersion(), but psycopg2 not implement them.

other way is use "show server_version" insted of "select version()".

testdb=# show server_version;
 server_version

 8.3.3
