Postgres connectivity with Django

[xcdruffle]

Hi,

I'm stuck with setting up PostgreSQL with Django
Every time I run Django server it shows :

File "C:\Python38\lib\site-packages\psycopg2\init.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: FATAL:  password authentication failed for user "Test"

Here the user "Test" is my OS username and I'm running the database with default postgres user and a "password" which I've already defined in my Django "settings.py"

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'postgres',
        'USERNAME': 'postgres',
        'PASSWORD': 'root',
        'HOST': 'localhost',
        'PORT': '5431',
    }
}

I tried using the :

ALTER USER user_name WITH PASSWORD "password";

But still the error persists.

I even tried editing the "pg_hba.conf" file and manually added "trust" method for all users on my "localhost" but no help.

I'm running Postgres12 on Windows 10

Can you please guide me through this in what I might be doing wrong?

Thanks!
