Невозможно подключить базу данных postgresql heroku к localhost

Question

Я пытаюсь работать над веб-приложением, разработанным кем-то еще на Heroku. Потянув исходный код, я установил PostgreSQL 9.3 на свой компьютер.

Пробовал импортировать существующую базу данных на Heroku, но это не похоже на работу:

$ export HEROKU_POSTGRES_IVORY_URL=postgres:///$(user) 

Пробовал использовать следующие параметры в моем database.yml файле:

development: 
    adapter: postgresql 
    database: app-dev 
    host: localhost 
    username: user 
    password: (password created when installing PostgreSQL) 

Но это произвел следующая ошибка при попытке запустить приложение локально:

Я был над инструкцией ионы на Heroku снова и снова и не могут найти решение. Я относительно новичок в этом, поэтому некоторые указатели будут высоко оценены!

Я разрабатываю приложение с Ruby on Rails, и я использую Windows.

Answer 1

Я рекомендую проверить файл pg_hba.conf первым, который для окон должны быть расположены по адресу:

C:\Program Files\PostgreSQL\9.3\data\pg_hba.conf

В нижней части файла вы должны увидеть что-то вдоль линий:

# TYPE DATABASE  USER   ADDRESS     METHOD 

# "local" is for Unix domain socket connections only 
local all    all          trust 
# IPv4 local connections: 
host all    all    127.0.0.1/32   trust 
# IPv6 local connections: 
host all    all    ::1/128     trust 

Ваш файл conf отличается от того, что выше?

• Если вы делаете какие-либо изменения в этот файл, не забудьте перезапустить Postgres
