# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
# name = value
#
# (The "=" is optional.) Whitespace may be used. Comments are introduced with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, run "pg_ctl reload", or execute
# "SELECT pg_reload_conf()". Some parameters, which are marked below,
# require a server shutdown and restart to take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run time
# with the "SET" SQL command.

我已经尝试了所有的解决方案。我什至无法在
pg_dumppg_dump database_name > database_backup.bakpg_dump: [archiver (db)] connection to database "database_name" failed: 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"?
请帮我解决这个问题。任何形式的帮助将不胜感激。预先感谢。
试试这个：
$ pg_lsclusters
如果您有这样的回复：
Ver Cluster Port Status Owner Data directory Log file
10 main 5432 down postgres /var/lib/postgresql/10/main /var/log/postgresql/postgresql-10-main.log
将访问权限更改为/var/lib/postgresql/10/main
$ sudo chmod 700 -R /var/lib/postgresql/10/main
重新启动
$ sudo -i -u postgres
$ /usr/lib/postgresql/10/bin/pg_ctl restart -D /var/lib/postgresql/10/main
那么，检查一下
$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
10 main 5432 online postgres /var/lib/postgresql/10/main /var/log/postgresql/postgresql-10-main.log
我遇到了类似的问题，但就我而言，我有多个集群，其中一个集群由我的用户拥有。
您可以在 pg_lsclusters 的输出中看到这一点。
在我的例子中，集群会启动，但使用
service start postgresql@15-clustername我认为原因是我的用户无权在
/run/postgresql也许您可以通过将用户添加到 postgres 组来解决，但我采取了稍微谨慎的方法，添加一个新组只是为了访问该文件夹并将我自己和 postgres 添加到该组。 这样我就不会无意中授予对更多我不需要的文件的访问权限。
注意我的系统上的路径与OP的不同，也许这是较新的postgres或操作系统。 我正在运行 ubuntu 22.04.4 和 postgres 15.8
#make a new group
sudo groupadd -r run_postgres
#add the users to the groups
sudo adduser postgres run_postgres
sudo adduser [your username] run_postgres
#apply the group to the folder where postgres wants to make the pid file
#-R is recursive so change group of files within... there will only be a handful v is verbose - it will list the files within
sudo chgrp -Rv run_postgres /run/postgresql
#/run/postgresql only had group read permissions so I needed to add write as well
# you can check this by doing `ls -l /run/ | grep postgres`
sudo chmod g+w /run/postgresql
我发现我不需要注销并重新登录才能正常工作，尽管 id 没有显示我的用户所在的组。
完成上述操作后，您可以通过
进行检查sudo service postgresql@clustername stop
sudo service postgresql@clustername start
启动现在应该可以干净地运行，不再挂起，并且有关无法在 syslog 中生成 .pid 文件的错误消息不应再出现。
启动后执行
ls -l /run/postgresql可能有一种方法可以在 postgres 配置中修复此问题或更改集群的所有者，但这是工作项目的本地数据库的标准设置，并且可能会在数据库所在的不同方向上导致进一步的权限问题我的主目录！
