Psycopg 2 is one of the most popular PostgreSQL drivers for Python. It is compliant to the Python's DB-API 2.0 specification. It is mostly implemented in C and uses the libpq library. It is thread-safe, which means that you can share the same connection object between several threads. It can work both with Python 2 and Python 3.
The official web page of the library is located at http://initd.org/psycopg/.
The psycopg2 driver can be installed with pip on Linux from the command line, as follows:
