Hi Devrim, I am using 9.5 psql to connect to 9.5 instance which is not working. You said "We changed the default socket directory from /tmp to /var/run/postgresql". Could you point this to me in documentation please?

I think you are using 9.3's psql to connect to 9.5 instance. That won't work for the RPMs (unless you specify -h option as stated in the thread). We changed the default socket directory from /tmp to /var/run/postgresql. Please use 9.5's psql.
