Hi all,
Is there a way to view the list of all tables from python (or any other
languages for that matter) DB-API? What I'm looking for is a command
similar to the meta-command '\d' that works with the psql client.
Thanks very much!
Dan

Try \d under psql -E sometime. It'll give you the query it uses.

There's also the INFORMATION_SCHEMA:

Quick note. The INFORMATION_SCHEMA should stay pretty static from one
pgsql version to the next, while the queries that psql -E shows will
likely change from one version to another.

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)]
