Thank you very much, Momjian. 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.
