Trying to connect to posgresql base as Django wrote in its docs: https://docs.djangoproject.com/en/5.1/ref/databases/#postgresql-notes DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "OPTIONS": { "service": "my_service", "passfile": ".my_pgpass", }, } }  I've created 2 files in my home directory .pg_service.conf [my_service] host=/var/run/postgresql user=dbms dbname=dbms_db port=5432  .pgpass /var/run/postgresql:5432:dbms_db:dbms:my_password  Such command as test of .pgpass:  psql -h localhost -U dbms dbms_db  is working. But the connect doesn't work: DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "OPTIONS": { "service": "my_service", "passfile": ".pgpass", }, } }  with such error  Traceback (most recent call last): File "/home/www/projects/amodulesu/venv/lib/python3.11/site-packages/django/db/backends/base/base.py", line 279, in ensure_connection self.connect() File "/home/www/projects/amodulesu/venv/lib/python3.11/site-packages/django/utils/asyncio.py", line 26, in inner return func(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^ File "/home/www/projects/amodulesu/venv/lib/python3.11/site-packages/django/db/backends/base/base.py", line 256, in connect self.connection = self.get_new_connection(conn_params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/www/projects/amodulesu/venv/lib/python3.11/site-packages/django/utils/asyncio.py", line 26, in inner return func(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^ File "/home/www/projects/amodulesu/venv/lib/python3.11/site-packages/django/db/backends/postgresql/base.py", line 332, in get_new_connection connection = self.Database.connect(**conn_params) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/www/projects/amodulesu/venv/lib/python3.11/site-packages/psycopg/connection.py", line 119, in connect raise last_ex.with_traceback(None) psycopg.OperationalError: connection failed: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL: Peer authentication failed for user "dbms" ...

Trying to use export vars in debian - but it doesnt work too.. Here is pg_hba.conf 
Cant use  'service': 'my_service', 'passfile': '.pgpass',  So use decouple and tradional DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'dbms_db', 'USER': 'dbms', 'PASSWORD': DB_PASS, 'HOST': '127.0.0.1', 'PORT': '5432', } }
