我在台式计算机上安装了postgresql，只添加了512 GB SSD驱动器 . 我以为我会将数据迁移到SSD，所以我按照这些说明https://www.digitalocean.com/community/tutorials/how-to-move-a-postgresql-data-directory-to-a-new-location-on-ubuntu-16-04 .

现在，当我尝试使用psql登录postgres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"?

以下是sudo systemctl status postgresql的结果

postgresql.service - PostgreSQL RDBMS

以下是pg_lsclusters的结果

Ver Cluster Port Status Owner Datadirectory      Log file

这里还有systemctl status postgresql@9.6-main.service的结果

和ps auxw | grep postgres

rowanga+ 11942  0.0  0.0  14224   944 pts/4    S+   08:36   0:00 grep --color=auto postgres

当我跑; /usr/lib/postgresql/9.6/bin/postgres -d 1 -D /mnt/ssd/postgresql/9.6/main -c config_file = / etc / postgresql / 9.6 / main / postgresql.conf

启动过程卡在我的三个数据库的autovacuum循环中：

有人知道怎么修这个东西吗？

postgresql postgis
