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"?

I uninstalled and installed postgresql but nothing works for me.

$ sudo service postgresql start
 * Starting PostgreSQL 10 database server                                                                                                       
 * Failed to issue method call: Unit [email protected] failed to load: No such file or directory. See system logs and 'systemctl status [email protected]' for details.

systemctl status postgresql

Make sure you add your server to your PostgreSQL\9.4\data\pg_hba.conf file – Juan Carlos Oropeza

Is it a new installation or an upgrade? Is this on linux? I also advise to move the question to dba.stackexchange.com since the question is not related to programming. – kometen

This problem /var/run/postgresql/.s.PGSQL.5432 is about permission,

did you change the database directory? if yes so you need to give write and read permission to the postgres

sudo chown -R postgres:postgres <directory_path>

or

sudo chmod -R 777 <directory_path>

case you cannot use remote access, on pg_config edit this line listen_addresses = 'localhost' to listen_addresses = '*'

and in the pg_hba.conf insert this line: 

host    all  all  0.0.0.0/0  md5
