Postgresql更改数据目录和套接字错误

Question

当我在

/etc/postgresql/9.5/main/postgresql.conf

表单默认路径

/var/lib/postgresql/9.5/main

按照我的习惯

/home/用户/postgresql/9.5/main

使用本手册https://www.digitalocean.com/community/tutorials/how-to-move-a-postgresql-data-directory-to-a-new-location-on-ubuntu-16-04

我有错误：

psql：无法连接到服务器：没有此文件或目录服务器是否在本地运行并接受 Unix 域套接字“/var/run/postgresql/.s.PGSQL.5432”上的连接？

当我错了？
