Re: Postgres open source upgrades

I also tried to test a minor upgrade with online documentation I found. I implemented the below steps for upgrading from 14.1 to 14.2 and this is open source.
Before upgrade binary location is /postgres/14
1. Stop the cluster
2. Rename old binary location to /postgres/14.old
3. Create new binary location /postgres/14.2
4. Untar the software,
Configure in the new directory 14.2 with new unrated software
Make world
Make install-world
5. Rename /postgres/14.2 to /postgres/14
6. Start the cluster
Cluster started and I was able to connect remotely with no issues. However when I tried using psql, I got below error:
Connection to server on socket “/var/run/postgresql/.s.PGSQL.5432” failed.
But my postgres has been using socket file in /tmp location before upgrade. I am not sure why after upgrade psql is searching at a different allocation for socket.
Can someone help me here?
Are the steps that I did, correct??

Thanks and Regards,
J. Teja Sri.
