A quick ddg search revealed:

sudo ss -tulpn
Netid  State      Recv-Q Send-Q Local Address:Port               Peer Address:Port
tcp    LISTEN     0      128     ::1:5432                 :::*                   users:(("postgres",pid=21794,fd=3))

Is the correct conclusion from this output, that the port 5432 is open?
