PG：ConnectBad Rails 4 Postgresql

我知道，似乎這個問題已被問及上百次，但這次我認爲它是不同的。PG：ConnectBad Rails 4 Postgresql

當我重新啓動我的Mac和運行軌道s，該網站工作正常。

➜ BankingApp git:(master) ✗ which psql 
/Applications/Postgres.app/Contents/MacOS/bin/psql 
➜ BankingApp git:(master) ✗ which postgres 
/Applications/Postgres.app/Contents/MacOS/bin/postgres

但是，當我重新啓動服務器時，它每次都會出現此錯誤。

我使用的是osx山獅和Postgres.app。我也在使用使用.zshrc的omyzsh。在那個文件中我有：

PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH" 
export PGHOST=localhost

我也有Postgres.app運行。

的database.yml

development: 
    adapter: postgresql 
    database: BankingApp 
    pool: 5 
    timeout: 5000

如果我打開與pgAdmin的3數據庫，我可以從表等，這似乎是工作選擇。我認爲必須有一個流氓程序出現這個錯誤。

could not connect to server: No such file or directory Is the server running locally and     accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?
