Have a look at the docs about the settings file: https://docs.djangoproject.com/en/4.1/topics/settings/

Look for a section like this one:

    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.postgresql',
            'NAME': YOUR_DB_NAME,
            'USER': USERNAME,
            'PASSWORD': PASSWORD_FOR_DB,
            'HOST': 'localhost'  // in Development.
        }
    }

and then change the NAME , USER , PASSWORD and HOST values to the ones you need.
