Question

[Ubuntu 16.04] 我安装了postgresql 9.5以及依赖项：

sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main' > /etc/apt/sources.list.d/pgdg.list"
wget --quiet -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-common
sudo apt-get install postgresql-9.5 libpq-dev

当我想运行psql时，我得到：

psql: 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"?

但是/var/run/postgresql/是空的。当我重新启动posgresql时，一切似乎都很好：

$ /etc/init.d/postgresql restart
[ ok ] Restarting postgresql (via systemctl): postgresql.service.

$ /etc/init.d/postgresql status
● postgresql.service - PostgreSQL RDBMS
   Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)
   Active: active (exited) since wto 2016-09-27 16:18:26 CEST; 1min 15s ago
  Process: 3076 ExecReload=/bin/true (code=exited, status=0/SUCCESS)
  Process: 3523 ExecStart=/bin/true (code=exited, status=0/SUCCESS)
 Main PID: 3523 (code=exited, status=0/SUCCESS)

但如果检查ps aux没有这样的PID（为什么??）

完全重新安装并没有任何帮助。我该如何解决？

编辑：

我刚注意到然后键入/etc/init.d/postgresql force-reload postgresql，systemctl有一段时间，然后被自动杀死

除了systemctl返回

postgresql.service         loaded active exited    PostgreSQL RDBMS
● postgresql@9.5-main.service loaded failed failed    PostgreSQL Cluster 9.5-main

为什么会失败？

Postgresql服务器无法启动
