Question

重新创建错误的步骤：

brew uninstall postgresql
brew prune
brew install postgresql
运行postgresql启动命令
psql

的产率：

psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

我尝试过的建议修复不起作用

create missing symbolic link:

sudo mkdir /var/pgsql_socket/
sudo ln -s /private/tmp/.s.PGSQL.5432 /var/pgsql_socket/

删除postmaster.pid文件（与上面相同的链接）：

rm /usr/local/var/postgres/postmaster.pid

create potentially "cleaned up" directories from upgrade:

mkdir -p /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/ touch /usr/local/var/postgres/{pg_tblspc,pg_twophase,pg_stat_tmp}/.keep

修改1：

This article正确推测有多个版本的postgres正在使用，并且必须指定pg_ctl（下方）。奇怪的是，/usr/local/var中有两个目录：postgre＆amp; postgres。如果有人知道要更新哪些设置以直接使用正确的pg_ctl命令，我将不胜感激！

/usr/local/Cellar/postgresql/9.3.5_1/bin/pg_ctl -D /usr/local/var/postgre start

我遇到了同样的问题，在查看日志文件后发现一个目录丢失了：

$ tail /usr/local/var/postgres/server.log
FATAL:  could not open directory "pg_tblspc": No such file or directory

然后我做了$ mkdir /usr/local/var/postgres/pg_tblspc，重新启动了PostgreSQL并得到了：

$ tail /usr/local/var/postgres/server.log
FATAL:  could not open directory "pg_replslot": No such file or directory

重做过程后，我可能会创建以下目录，然后成功启动PostgreSQL：

/usr/local/var/postgres/pg_tblspc
/usr/local/var/postgres/pg_replslot
/usr/local/var/postgres/pg_twophase
/usr/local/var/postgres/pg_logical
/usr/local/var/postgres/pg_logical/mappings

我希望这会有所帮助。
