Hi,
I’m deploying my app and i get an error related to postgres connection, error is 
psycopg2.OperationalError: could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5433?
before that, the Travis log says
/home/travis/virtualenv/python3.6.7/lib/python3.6/site-packages/django/db/backends/postgresql/base.py:270: RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests). Django was unable to create a connection to the 'postgres' database and will use the first PostgreSQL database instead.
as i’m using Pipenv i did create a .travis file like below
language: python
python:
- '3.6.7'
# safelist
branches:
only:
- staging
services:
- postgresql
env: DJANGO_SETTINGS_MODULE=purbeurre.settings.travis
before_install:
- sudo service postgresql stop
- sed -e 's/^port.*/port = 5433/' /etc/postgresql/10/main/postgresql.conf > postgresql.conf
- sudo chown postgres postgresql.conf
- sudo mv postgresql.conf /etc/postgresql/10/main
- sudo service postgresql start 10
install:
- make init
script:
- make test
and the corresponding Makefile
help:
@echo ' init'
@echo ' install pipenv and all project dependencies'
@echo ' test'
@echo ' run all tests'
init:
@echo 'Install python dependencies'
pip install pipenv
pipenv install
test:
@echo 'Run all tests'
pipenv run python manage.py test
Can you help understand this error and help me to fix it ?
