[Buildroot] [PATCH v3 2/2] python-psycopg2: new package

[Adam Duskett <aduskett@gmail.com>]

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 INSERTs or UPDATEs.

+	  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

+
+	  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 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.
