PostgreSQL：我更改了位置，它不再启动

Question

我尝试按照建议的here更改postgresql的文件夹位置

但是如果我尝试：

sudo -u postgres psql

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"

新位置在：

/home/database/postgresql
