per the documentation to listen for client connections on a given IP address you set listen_addresses to a commaspearated list of IP addresses in postgresql.conf
That line is commented out in the default conf file, when I uncomment it, and add the address, then do sudo systemctl restart postgresql the postgres processes are not running afterwards. root@dhbpostgres:/home/johnson# ps -aux | grep postgres root 1452 0.0 0.0 6608 2364 pts/1 S+ 19:07 0:00 grep --color=auto postgres root@dhbpostgres:/home/johnson# vi /etc/postgresql/15/main/postgresql.conf <<commented out listen_addresses root@dhbpostgres:/home/johnson# systemctl restart postgresql root@dhbpostgres:/home/johnson# ps -aux | grep postgres postgres 1461 0.2 0.1 219220 30568 ?
