non-US, sic).

Description: Python module for PostgreSQL
psycopg is a PostgreSQL database adapter for the Python programming language
(just like pygresql and popy.) This is version 2, a complete rewrite of the
original code to provide new-style classes for connection and cursor objects
and other sweet candies. Like the original, psycopg 2 was written with the
aim of being very small and fast, and stable as a rock.
.
psycopg is different from the other database adapter because it was designed
for heavily multi-threaded applications that create and destroy lots of
cursors and make a conspicuous number of concurrent INSERTs or UPDATEs.
psycopg 2 also provides full asycronous operations for the really brave
programmer.
.
The main advantages of psycopg2 are that it supports the full Python DBAPI-2.0
and being thread safe at level 2. It also includes some extensions to the
standard DBAPI-2.0 to allow for better thread performance.

==========
psycopg2da
==========
This file outlines the basics of using Zope3 with PostgreSQL via PsycopgDA.
Installing PsycopgDA
--------------------
1. Check out the psycopg2da package into a directory in your
PYTHONPATH. INSTANCE_HOME/lib/python or Zope3/src is usually the
most convenient place:
svn co svn://svn.zope.org/repos/main/psycopg2da/trunk psycopg2da
2. Copy `psycopg2-configure.zcml` to the `package-includes` directory
of your Zope instance.
Creating Database Connections
------------------------------
It is time to add some connections. A connection in Zope 3 is
registered as a utility.
3. Open a web browser on your Zope root folder (http://localhost:8080/
if you use the default settings in zope.conf.in).
4. Click on the 'Manage Site' action on the right side of the
screen. You should see a screen which reads 'Common Site Management
Tasks'
5. Around the middle of that page, you should see a link named 'Add
Utility'. Click on it.
6. Select 'Psycopg DA' and type in a name at the bottom of the page.
7. Enter the database connection string. It looks like this:
dbi://username:password@host:port/databasename
8. Click on the 'Add' button.
9. You should be on a page which reads 'Add Database Connection
Registration'. There you can configure the permission needed to use
the database connection, the name of the registration and the
registration status. You can use any name for 'Register As' field,
as long as it doesn't clash with an existing one. Choose a
permission. Choose between 'Registered' and 'Active' for the
'Registration Status'. Only one component of a kind can be 'Active'
at a time, so be careful.
10. You should be redirected to the 'Edit' screen of the connection
utility.
11. If you want to, you can go to the Test page and execute arbitrary
SQL queries to see whether the connection is working as expected.
Using SQL Scripts
-----------------
You can create SQL Scripts in the content space. For example:
12. Go to Zope root.
13. Add an SQL script (you can use the Common Tasks box on the left,
or the Add action on the right).
14. Click on the name of your new SQL script.
15. Choose a connection name (the one you entered in step 29) from the
drop-down.
16. Enter your query and click on the 'Save Changes' button.
17. You can test the script in the -- surprise! -- Test page.
