We haven't upgraded our Trac in some time, so we're still using a
slightly older 0.11-dev, but recently we have been having regular --
often daily -- episodes where our PostgreSQL connection starts throwing


    File 
"/usr/local/lib/python2.5/site-packages/django/db/backends/postgresql_psycopg2/base.py",
 line 69, in _cursor
      self.connection = Database.connect(conn_string, **self.options)

  OperationalError: FATAL:  connection limit exceeded for non-superusers


Obviously something is leaking DB connections.  This does seem a bit
familiar.
