9.4. Database wrapper class: DB

pg module contains a class called DB. All pgobject methods are included in this class also. A number of additional DB class methods are described below. The preferred way to use this module is as follows (See description of the initialization method below.):

import pg

db = pg.DB(...)

for r in db.query(
    "SELECT foo,bar
       FROM foo_bar_table
      WHERE foo !~ bar"
    ).dictresult():

    print '%(foo)s %(bar)s' % r

The following describes the methods and variables of this class.

The DB class is initialized with the same arguments as the pg.connect method. It also initializes a few internal variables. The statement db = DB() will open the local database with the name of the user just like pg.connect() does.
