No /var/run/postgresql/.s.PGSQL after reboot (Ubuntu)

Rebooting the server, bumped into the following error, preventing my django server from functioning: psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.xxxx" failed: No such file or directory

Not to easy to search the solution, tons of search spam (and of course stupid advises "purge porstgresql including databases and all the files and reinstall".

$ sudo -i -u postgres $ /usr/lib/postgresql/14/bin/pg_ctl restart -D /var/lib/postgresql/14/main
