我按照这篇文章安装了postgres https://gorails.com/setup/ubuntu/15.04
但是我在尝试启动 postgresql 时遇到此错误
vihaan@trojan:~$ sudo -u postgres createuser vihaan -s
createuser: could not connect to database postgres: 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"?
以下是来自 postgres 软件包安装的消息。
