The cursor object has a "description" data member.
Look at the DB-API spec: http://www.python.org/dev/peps/pep-0249/
under "Cursor Objects".
Python 2.3.3 (#1, Jan 3 2004, 07:17:11)
[GCC 3.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pgdb
>>> db=pgdb.connect(database='pigrestore', host='ivy')
>>> cur=db.cursor()
>>> cur.execute('select * from machine')
>>> print cur.description
[('machine_name', 'text', -1, -1, None, None, None), ('machine_id', 'int2', -1,
2, None, None, None), ('area', 'text', -1, -1, None, None, None), ('text',
'text', -1, -1, None, None, None)]
