PostgreSQL database adapter for the Python programming language
54d904138d
This makes possible to import _psycopg directly, after adding the
package directory to the pythonpath. This enables hacks such as:
sys.path.insert(0, '/path/to/psycopg2')
import _psycopg
sys.modules['psycopg2._psycopg'] = _psycopg
sys.path.pop(0)
which can work around e.g. the problem of #201, freeze that cannot
freeze psycopg2. Well, freeze cannot freeze it because it's just not
designed to deal with C extensions. At least now the frozen application
can hack the pythonpath and work around the limitation by importing
_psycopg as above and then doing the rest of the imports normally.
Keeping long-lived references to python objects is bad anyway: the
tz module couldn't be reloaded before.

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__.
