Logged by:          Richard Devey

PostgreSQL version: Unsupported/Unknown
Operating system:   Oracle Linux 8
Description:

The scripts for this installation call on a directory named "13" in this
location:
download.postgresql.org/pub/repos/yum/

That directory is missing which is causing Azure ARC installations to fail.

Full path is:
https://download.postgresql.org/pub/repos/yum/13/redhat/rhel-8-x86_64/repodata/repomd.xml
