[BUG] Postgres needed for install to run correctly

[bipin-lekhak]

Describe the bug
The install requires postgres to be installed in the system before running pip-install. If postgres is not installed, psycopg2 building fails with error:

Error: pg_config executable not found.

Please add the directory containing pg_config to the PATH

or specify the full executable path with the option:



    python setup.py build_ext --pg-config /path/to/pg_config build ...



or with the pg_config option in 'setup.cfg'.

To Reproduce
Steps to reproduce the behavior:

1. Try a fresh installation on a new system or an empty docker container

Desktop (please complete the following information):

• OS: [e.g. iOS]: OSx

I solved the issue with this Stack Overflow answer
But I think the nest way is to have all dependencies installed as part of the project, or at least mentioned in the README.
