The idea is to release a package 'psycopg2-binary' to allow installing binary, and leave the psycopg2 package to be source only, to avoid pushing the unreliability of the wheel pacakge by default (see issue #543). Version number bumped to test with new packages.

"""Python-PostgreSQL Database Adapter
|
|
|
|
psycopg2 is a PostgreSQL database adapter for the Python programming
|
|
language. psycopg2 was written with the aim of being very small and fast,
|
|
and stable as a rock.
|
|
|
|
psycopg2 is different from the other database adapter because it was
|
|
designed for heavily multi-threaded applications that create and destroy
|
|
lots of cursors and make a conspicuous number of concurrent INSERTs or
|
|
UPDATEs. psycopg2 also provide full asynchronous operations and support
|
|
for coroutine libraries.
