Thread: Postgres Version want to update from 9.2 to 9.5 version in CentOS 7.9

Postgres Version want to update from 9.2 to 9.5 version in CentOS 7.9

Hi,

Problem: Having multiple versions of Postgres installed in CentOS 7. I Want to set the 9.5 version as default. Not able to access Postgres 9.5 through the terminal as well.
  1. For Command psql --version I'm getting 9.5 as the version.
  2. For Command sudo -u postgres psql I'm getting 9.2 as the version.
Please look at the below screenshot.

Background: By default, the server has a 9.2 version I installed the rh-postgresql95 version from the below article.
Used the below command to install rh-postgresql95
yum --enablerepo=centos-sclo-rh -y install rh-postgresql95-postgresql-server

Tried updating the PATH variable correctly with the latest version. But not working.

Please share the steps or any guidance on how to resolve the issue.

Thankyou so much. Anything would be helpful.

Thanks & Regards,

You'd need to read up on Red Hat's "SCL" packaging system to understand
how to use that rh-postgresql95 package.  SCL is since my time there,
but I'm pretty sure it's intentional that it's not in the default PATH.

But TBH, all the versions available from Red Hat for RHEL7/CentOS7 are
out of support as far as the upstream community is concerned; to us it's
pretty mystifying why you'd be trying to migrate to an already-years-dead
release branch.  I'd suggest getting some more modern release from
https://www.postgresql.org/download/

            regards, tom lane

Thank you for the quick response.

Yes, I'm willing to get the latest version. I read some articles CentOS 7 doesn't support the latest versions. So was trying the old versions.

I tried the article shared but, got the below error at the step.

Something is wrong here.

Please suggest the steps for resolving this issue.

You have bigger problems to solve with your setup. Basic programs are failing to run, so there are other things that need fixing with your package manager that are completely unrelated to PostgreSQL.

Although Tom kindly responded to your initial question, this list (-hackers) is the wrong place to be asking that type of question, as its purpose is to discuss the *development* of PostgreSQL, not installation and upgrade issues.

There are many other places better suited to your question, including the pgsql-general list [1], IRC channel [2] and Slack channel [3].
