[ Solved ] Share PostgreSQL Database Between Two Ubuntu 16.04 Based Machines

[WALLONN7]

Machine one - Client working as a Server

·         Postgresql Contrib installed and database called “stoq” created.

·         Localhost, user “mho”, password required and Port 5432.

·         Trade automation program installed.

 

Machine two – Client working as a Terminal

·         PostgreSQL common installed.

·         Same Trade automation program installed.

 

I can do all the usual procedures through machine one.
My request for help is to set both machines in order to do everything necessary also through the machine two. There's a router between those machines.
I emphasize:

 

I’m novice user in Linux environment. And I ask that the answers are the most intelligible and practices.

 

In case you need more information, don’t hesitate to ask for!
