	# DATABASE CONFIGURATION
	# ------------------------------------------------------------------------------
	DATABASES['default']['NAME'] = get_secret('POSTGRES_DB')
	DATABASES['default']['USER'] = get_secret('POSTGRES_USER')
	DATABASES['default']['PASSWORD'] = get_secret('POSTGRES_PASSWORD')
	DATABASES['default']['HOST'] = get_secret('DATABASE_HOST')
	DATABASES['default']['PORT'] = get_secret('DATABASE_PORT')

It would be more convenient if there was one environment variable like DATABASE_URI=postgresql://chris:chris1234@localhost:5432/chris
