PostgreSQL database adapter for the Python programming language

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__. .. __: http://initd.org/psycopg/docs/install.html For any other resource (source code repository, bug tracker, mailing list) please check the `project homepage`__. .. __: http://initd.org/psycopg/
