Hmm, something odd there, because a port number mismatch should have
resulted in psql failing to connect via unix socket either.  Maybe
you have more than one active postmaster?

"ps xauwww | grep postgres" shows only one postgres process (and a few vaccum related)

 

yes, I see your point. makes sense. the unix socket is actually also on 5433

root@deb10tp:~# grep -nr 543 /etc/postgresql
/etc/postgresql/11/main/postgresql.conf:63:port = 5433
root@deb10tp:~# find /var/run/postgresql/ | grep 543
/var/run/postgresql/.s.PGSQL.5433
/var/run/postgresql/.s.PGSQL.5433.lock
root@deb10tp:~#

 

Anyway, given these settings, "psql -p 5433 -h localhost" should
connect.  If you still get "connection refused" then you need to
look at the kernel firewall (packet filter) settings.

yes, with "-p 5433" I can connect
