Replace psycopg2 with psycopg2-binary

To avoid `No matching distribution found for psycopg2`, I use an alternative from [Psycopg2 web page](https://www.psycopg.org/docs/install.html#quick-install).
It is the quickest way to install Psycopg by using the wheel package available on PyPI in most operating systems.
