- 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`__.

- For any other resource (source code repository, bug tracker, mailing list)
- please check the `project homepage`__.

- Installation
- ------------
- Building Psycopg requires a few prerequisites (a C compiler, some development
- packages): please check the install_ and the faq_ documents in the ``doc`` dir
- or online for the details.
- If prerequisites are met, you can install psycopg like any other Python
- package, using ``pip`` to download it from PyPI_::
- $ pip install psycopg2
- or using ``setup.py`` if you have downloaded the source package locally::
- $ python setup.py build
- $ sudo python setup.py install
- You can also obtain a stand-alone package, not requiring a compiler or
- external libraries, by installing the `psycopg2-binary`_ package from PyPI::
- $ pip install psycopg2-binary
- The binary package is a practical choice for development and testing but in
- production it is advised to use the package built from sources.
