Rudder

I try to install a Rudder server on RHEL8, but I get this following error:

root@server:~# cat /etc/yum.repos.d/rudder.repo

Error: 
 Problem: package rudder-server-8.0.0.alpha2.git202308180211-1.EL.8.x86_64 requires postgresql-server >= 13, but none of the providers can be installed

This is awaited because Rudder 8.0 required postgres 13. We need to document:

- add postgresql repo:

dnf install https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm

- disable base postgresql repos:

dnf module disable postgresql

Install rudder server:

dnf install rudder-server
