Daniele Varrazzo 600c744fba Work in progress on writable encoding Would help using adapt(unicode) to quote strings without a connection, see ticket #331. Currently in heisenbug state: if test_connection_wins_anyway and test_encoding_default run (in this order), the latter fail because the returned value is "'\xe8 '", with an extra space. Skipping the first test, the second succeed. The bad value is returned by the libpq: ql = PQescapeString(to+eq+1, from, len); just returns len = 2 and an extra space in the string... meh.		2016-07-01 11:17:55 +01:00

psycopg2 - Python-PostgreSQL Database Adapter
=============================================

Psycopg is the most popular PostgreSQL database adapter for the Python
programming language.  Its main features are the complete implementation of
the Python DB API 2.0 specification and the thread safety (several threads can
share the same connection).  It was designed for heavily multi-threaded
applications that create and destroy lots of cursors and make a large number
of concurrent "INSERT"s or "UPDATE"s.

Psycopg 2 is mostly implemented in C as a libpq wrapper, resulting in being
both efficient and secure.  It features client-side and server-side cursors,
asynchronous communication and notifications, "COPY TO/COPY FROM" support.
Many Python types are supported out-of-the-box and adapted to matching
PostgreSQL data types; adaptation can be extended and customized thanks to a
flexible objects adaptation system.

Psycopg 2 is both Unicode and Python 3 friendly.


Documentation
-------------

Documentation is included in the 'doc' directory and is `available online`__.

.. __: http://initd.org/psycopg/docs/


Installation
------------

If all the dependencies are met (i.e. you have the Python and libpq
development packages installed in your system) the standard::

    python setup.py build
    sudo python setup.py install

should work no problem.  In case you have any problem check the 'install' and
the 'faq' documents in the docs or online__.
