Ruby on Rails and Postgresql - Server is running, but I'm obtaining a could not connect to server error

Tag : ruby-on-rails , By : Revision17

hop of those help? You need to add port: 5433 to your database.yml.
The default PostgreSQL port is 5432, but your pg_lsclusters command says the server is running on 5433. This is why Rails can’t find a server running on localhost:5432.

this will help Okay so I found the solution:
I replaced this code in my settings.py file:
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'myDB',
        'USER': 'loicq',
        'PASSWORD': '*********',
        'HOST': 'localhost',
        'PORT': '',
DATABASES = {'default': dj_database_url.config(default='postgres://YOURUSER:YOURPASSWORD@YOURHOST:5432/YOURDATABASENAME')}
pip install dj_database_url

Connect to Hive database tables using postgresql-fdw from postgresql server

wish help you to fix your issue postgres_fdw is for connecting to other PostgreSQL instances. Hive doesn't use the same wire protocol as PostgreSQL does, so surely postgres_fdw would not be expected to connect to it successfully. Perhaps you can try https://github.com/youngwookim/hive-fdw-for-postgresql or https://sourceforge.net/projects/hadoopfdw/.
