Ошибка при переносе или создании базы данных с использованием Postgres

/ 28 апреля 2020

прежде чем я начну, я очень новичок в этом, я не имею в виду дезинформировать кого-либо, я просто новичок в переполнении стека.

пытается настроить базу данных postgresql, при запуске команды rails db: setup Postgres установлена. Кто-нибудь знает проблему? 

could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
Couldn't create 'db/mcl-development' database. Please check your configuration.
rails aborted!

Вот так выглядит мой файл базы данных, я следовал учебному пособию: 

default: &default
  adapter: postgresql
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  timeout: 5000

development:
  <<: *default
  database: db/mcl-development

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: db/mcl-test

production:
  <<: *default
  database: db/mcl-production

Я запустил команду sudo service postgresql start и это в консоли ничего не показывалось, он просто перешел на новую строку, затем я сделал rails s и получил следующую ошибку в localhlost:

PG :: ConnectionBad FATAL: роль "root" не существует Извлеченный источник (вокруг строки # 45): 

### Convenience alias for PG::Connection.new.

    return PG::Connection.new( *args )
