PgBouncer doubts

Hi,

I'm trying PgBouncer for the first time with a simple Python web
application (Flask + psycopg2), and I have a hard time interpreting
the meaning of its log messages by simple googling. I'm basically
seeing a bunch of:

2014-06-09 09:25:07.867 20980 LOG C-0x1b1b240: vinum/vinum(at)unix:6432

I find these multiple closings with "age=0" worrying, do they mean
that the connections are always recreated, thus never pooled?

My Flask/psycopg2 connection handling code is super simple:

@app.before_request
def before_request():
rdc = psycopg2.extras.RealDictConnection
g.db = psycopg2.connect("dbname=%s user=%s port=%s" %
(app.config['DATABASE_NAME'],
app.config['DATABASE_USER'],
app.config['PGBOUNCER_PORT']),
connection_factory=rdc)

@app.teardown_request
def teardown_request(exception):
if hasattr(g, 'db'):
g.db.close()

I'd greatly appreciate any explanation or guidance about this
