move to `psycopg2-binary`?

Description

I tried to install your package from pip and got a usual Error: pg_config executable not found. because I don’t have libpq or postgres-devel packages.

I cloned your repo, replaced psycopg2 >= 2.7.4 with psycopg2-binary and installed it with python setup.py install command. It works like a charm and not requires postgres stuff now.

How about to move to psycopg2-binary?

Your environment

• Please provide your OS and version information. OS: Manjaro 18.0.4 Illyria Kernel: x86_64 Linux 5.1.16-1-MANJARO
• Please provide your CLI version. pgcli==2.1.1
• What is the output of pip freeze command. Clean virtualenv with pgcli==2.1.1 installed

This one worked for me as a workaround:

pip install pgcli --only-binary psycopg2

Interestingly psycopg2 recommends not using the binary version for production: http://initd.org/psycopg/docs/install.html#binary-install-from-pypi

If you are the maintainer of a publish package depending on psycopg2 you shouldn’t use ‘psycopg2-binary’ as a module dependency. For production use you are advised to use the source distribution.

Note

The binary packages come with their own versions of a few C libraries, among which libpq and libssl, which will be used regardless of other libraries available on the client: upgrading the system libraries will not upgrade the libraries used by psycopg2. Please build psycopg2 from source if you want to maintain binary upgradeability.

This makes sense, as annoying as it is.
