postgresql - cannot change "postgres" user

My postgres databse keeps the value postgres for NAME, USER, PASSWORD even when I create new db and new user. It seems that no matter what I do, I cannot alter it.

I use django and an ubuntu droplet.

Steps to reproduce: I add new user, give it admin rights, ensure OpenSSH is open.

Logged as the new user and:

Log into a postgres session-           `sudo -u postgres psql`
create new db:                     `CREATE DATABASE new_db;`
Create new user with a password        `CREATE USER dbuser WITH PASSWORD 'dbpsw';`
Alter the roles and grant it all priviliges. 

verify connection:

\c new_db

Yet, if I go the bash and retreive the values of the postgres database, Yet, my database stays the same:

NAME = postgres
Password = postgres
User = postgres

>>> DATABASES
{'default': {'ENGINE': 'django.db.backends.postgresql', 'NAME': 'postgres', 'USER': 'postgres', 'PASSWORD': 'postgres', 'HOST': 'localhost', 'PORT': 5432, 'ATOMIC_REQUESTS': False, 'AUTOCOMMIT': True, 'CONN_MAX_AGE': 0, 'CONN_HEALTH_CHECKS': False, 'OPTIONS': {}, 'TIME_ZONE': None, 'TEST': {'CHARSET': None, 'COLLATION': None, 'MIGRATE': True, 'MIRROR': None, 'NAME': None}}}

Any advice as how I can modify and enforce the new databse and user would be highly appreciated.
