When executing the `sudo` command above:

* as which user are you doing that (you can see that via `id`)?
* in which directory are you executing it  (you can see that via `pwd`)?
* what is the home directory of the postgres user (you can see that via 
`grep postgres /etc/passwd`)
* what does `ls -ld /var/run/postgresql/; ls -l 
/var/run/postgresql/.s.PGSQL.5432` show?

You also wrote:

- what does `journalctl -xeu postgresql` say?
- what does `tail -n 20 
/var/log/postgresql/postgresql-*-qgisclouddb.log` show?
