Trying to get Postgres working on a uby-rails-postgres-nginx-unicorn-512mb-nyc1-01 droplet

I am trying to get postgres working on my droplet.

If I do a port scan for the ip of 5432, it says the port is closed. If I try to access with PGAdminIII, I get an error of ‘server doesn’t listen’

If I do a psql \conninfo I get

You are connected to database “rails” as user “rails” via socket in “/var/run/postgresql” at port “5432”.

I am able to connect with psql and create a test table

rails=> create table test (test varchar (10) );
CREATE TABLE
rails=> /dt
rails-> \d
       List of relations
 Schema | Name | Type  | Owner
--------+------+-------+-------
 public | test | table | rails
(1 row)

rails->

I think the problem could be in my database.yml. Is this the correct code for production?

production:
  <<: *default
  database: rails
  username: rails
  password: <%= ENV['APP_DATABASE_PASSWORD'] %>

I’d appreciate any help in getting pg working
