Some -devel RPMs require a new repository

The PostgreSQL Global Development Group has released an update to all supported versions today -- so RPMs also got updated.

As of today's updates, if you are using RHEL/CentOS/OL 7, -devel subpackages in 11 and 12 require an extra repo to be enabled on your system for llvm and clang. Other distros and PostgreSQL versions are not affected. Please note that only -devel subpackage require this repo.

Here is the solution:

If you are using CentOS, please run:

yum -y install centos-release-scl

If you are running RHEL 7, please attach "Red Hat Developer Subscription", and then enable the following repo:

subscription-manager repos --enable rhel-7-server-devtools-rpms

Once you enable these repositories, you can update to the latest packages.

If you have any questions, please either email to pgsql-pkg-yum@postgresql.org, or create a ticket at our redmine.
