PGDG Repository for RHEL6 is bronen, populated with RHEL7 packages

Hi,

I recently tried to setup both PostgreSQL 9.5 and 9.6 using the PGDG
repositories and they are both broken. Trying to install postgresql-server
from these repositories results in YUM conflicts regarding those packages
depending on 'systemd-units' which is not available in RHEL6.

Initially I thought it could be a YUM cache problem, as I found similar
issues caused by that in the archives, but ended up finding out that the
packages actually depend on systemd-units.

First, all packages populated in the redhat/rhel-6-x86_64 repositories have
*rhel7* in their names, which itself does not mean they won't work, but in
a closer look we can see systemd-units on the actual package dependencies:

# yum install postgresql96-server
Loaded plugins: aliases, changelog, fastestmirror, kabi, presto, security,
tmprepo, verify, versionlock

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
