Wilson Mayers Thanks for the appreciation. I haven't came across the issue you are mentioning but keep in mind my postgres user is postgres and I am only getting password of db in this tutorial and username is hardcoded. Also please make sure your database.yml file has: <% if ENV[ "DB_HOST" ] %> host: <%= ENV[ "DB_HOST" ] %> username: postgres <% end %> for production db. Hoping this resolves your issue. If issue still persists, contact me and may be we can come to some solution together.
