7699	"postgresql8.3 on window ""select version()"" format"	anonymous	nobody	"   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
