How to migrate from Sqlite to PostgresSQL in Django? OperationalError - django

Question

I am learning to use Django through a tutorial in which we are developing a small project,
i'm trying to connect a PostgresSQL database and do the migrations,
but i have certain problems when doing 'python manage.py migrate' in the terminal
Settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'DEMO_TEST',
'USER' : 'postgresql',
'HOST': 'localhost',
'PASSWORD':'le123le123',
'PORT': '5432',
}
}
