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.

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:
