Django fe_sendauth: no password supplied error, unable to connect to postgres database

I am trying to provision a server with a django applciation with postgresql as its backend. After installing the required packages, database and environment when I try to run migrations, I get the following error ``` Traceback (most recent call last): File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/db/backends/base/base.py", line 213, in ensure_connection self.connect() File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/db/backends/base/base.py", line 189, in connect self.connection = self.get_new_connection(conn_params) File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/db/backends/postgresql/base.py", line 176, in get_new_connection connection = Database.connect(**conn_params) File "/var/envs/traveldbapi/lib/python3.4/site-packages/psycopg2/__init__.py", line 130, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) psycopg2.OperationalError: fe_sendauth: no password supplied The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 22, in <module> execute_from_command_line(sys.argv) File "/var/envs/traveldbapi/lib/python3.4/site-packages/django/core/management/__init__.py", line 363, in execute_from_command_line utility.execute() ==== ommitting some lines ==== connection = Database.connect(**conn_params) File "/var/envs/traveldbapi/lib/python3.4/site-packages/psycopg2/__init__.py", line 130, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) django.db.utils.OperationalError: fe_sendauth: no password supplied ``` I confirmed that the relevant `DATABASE` setting required for django are present: ``` DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'HOST': 'localhost', 'NAME': DATABASE_NAME, 'USER': DATABASE_USER, 'password': DATABASE_PASSWORD } } ``` I am not sure why this error is happening because this is the same setup I use on my local machine and it works. To confirm that there aren't any issues with my `pg_hba.conf` I started from a fresh installation. The config hasn't been modified in any way and the application user has the required privileges on the application database.
