Greg Ward 53c1607644 Always raise OperationalError when connection was closed externally. 
From the DB-API (https://www.python.org/dev/peps/pep-0249/):

  OperationalError

  Exception raised for errors that are related to the database's
  operation and not necessarily under the control of the programmer,
  e.g. an unexpected disconnect occurs, [...]

Additionally, psycopg2 was inconsistent, at least in the async case:
depending on how the "connection closed" error was reported from the
kernel to libpq, it would sometimes raise OperationalError and
sometimes DatabaseError. Now it always raises OperationalError.

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__.
