Hi Fabio, It used to work before, even without installing updates. I got two interfaces : private IP and localhost Selinux is disabled. I tried installing it from source, from git repo. Can't find the RPM, do you have any link for centos7? I tried both /etc/init.d and command line, same issue. Tried with a new user called pgbouncer, same issue This is the result of lsof : [root@cmd-dev1 /]# lsof -n | grep 6543 postmaste 80762 postgres 10r FIFO 0,9 0t0 665436 pipe postmaste 80762 postgres 11w FIFO 0,9 0t0 665436 pipe Thanks -- Sent from: http://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
