Error while running a project

[Nadhem Zmandar]

I am beginner with Django. I've downloaded an open source Django project to start learning and I've installed PostGres and PgAdmin and tested them.and I have checked all details in the settings.py (especially the password) to link the project to the database created on PgAdmin.

However when I run the project I have this error

PS D:\django\btre_project-master> python manage.py runserver

When running postgres, the postgres user is normally not a user that you can login via the psycopg2 connector with. You should use a specific user for the database that you want to connect to. The postgres user is a superuser and is normally connected to a local user that you need to login via.

Andréas
