Add startup script to start the postgres instance on a selected port (#…

…1901)

Just easier to manage multiple postgres instances this way.

This script will: 
1. set the port number you passed to it in the passport server .env
2. start the postgres instance with the selected port.
3. verify that you didnt try to use a already taken post, so you dont
have to guess.


Works only on unix based machines tho (and, i think, WSL. didnt check
tho)
