I installed django and installed the pydev plugin under eclipse. Then I downloaded the postgres(1.16.0) sql tool and installed that. Here are my settings:

Then I wanted to configure the setting file under django:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2' ,
'NAME': 'django',
'USER': 'postgres',
'PASSWORD': 'admin',
'HOST': '',
'PORT': '',
}
}
but when I do syncdb i get:
backend = load_backend(db['ENGINE'])
File "C:\Python27\lib\site-packages\django\db\utils.py", line 24, in load_backend
return import_module('.base', backend_name)
File "C:\Python27\lib\site-packages\django\utils\importlib.py", line 35, in import_module
__import__(name)
File "C:\Python27\lib\site-packages\django\db\backends\postgresql_psycopg2\base.py", line 13, in <module>
from django.db.backends.postgresql_psycopg2.creation import DatabaseCreation
File "C:\Python27\lib\site-packages\django\db\backends\postgresql_psycopg2\creation.py", line 1, in <module>
import psycopg2.extensions
ImportError: No module named psycopg2.extensions
What do I do wrong?
PS.: I am developing under win7 and eclipse juno
