New issue 4306: Create new install extra for `psycopg2-binary`

Alex Rothberg:

Right now there is an [install extra for `postgresql` which installs `psycopg2`](https://bitbucket.org/zzzeek/sqlalchemy/src/fb377229cd4c4e503bde9c44b78d30ad48f3cf7e/setup.py#lines-159) however due to changes in `psycopg2` the wheel [will now be published under a new package name `psycopg2-binary` ](http://initd.org/psycopg/articles/2018/02/08/psycopg-274-released/). I suggest adding a new extra `postgresql-binary` that will install the wheel.
