Install PostgreSQL (shell only)

sudo apt install postgresql

Accessing the root role set up by default on PostgreSQL

sudo -u postgres psql

This will access PostgreSQL role that will help up setup our role and database

Creating our user | database Role

CREATE USER <rone_name> WITH SUPERUSER PASSWORD <role_password>;

This will create a super user role with your specified password.

I prefer creating a super user role on my newly installed PostgreSQL

Creating a database and setting the previously created Role

CREATE DATABASE <db_name> OWNER <role_of_choice>;

This will create a database and set the role as the owner. This will allow you to login directly to the database.

Setting up peer connection auth

sudo vi /etc/postgresql/<version>/main/pg_hba.conf

Now go to connections and add auth method to your role alternatively you can reset all roles auth method.

# TYPE          DATABASE          USER            ADDRESS        MTEHOD
	local         all               <your_role>     <address>      md5

This configuration will allow you to access the database with the password either using the psql shell or from an app.

Saving and loading the changes

sudo systemctl restart postgresql

Now you can access the database with your role name and password

# eg
psql -d <created_database> -U <created_role>
