Hi folks

After:

sudo yum install
http://yum.postgresql.org/9.4/redhat/rhel-6-x86_64/pgdg-redhat94-9.4-1.noarch.rpm

on a fresh RHEL6:

[ec2-user@ip-10-150-57-178 x86_64]$ uname -a
Linux ip-10-150-57-178 2.6.32-431.11.2.el6.x86_64 #1 SMP Mon Mar 3
13:32:45 EST 2014 x86_64 x86_64 x86_64 GNU/Linux
[ec2-user@ip-10-150-57-178 x86_64]$ lsb_release -a
LSB Version:
:base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Distributor ID: RedHatEnterpriseServer
Description:    Red Hat Enterprise Linux Server release 6.5 (Santiago)
Release:        6.5
Codename:       Santiago

"yum update" is failing with:

Error: Package: 1:nfs-utils-1.2.3-39.el6.x86_64 (installed)
           Requires: libevent-1.4.so.2()(64bit)
           Removing: libevent-1.4.13-4.el6.x86_64 (installed)
               libevent-1.4.so.2()(64bit)
           Updated By: libevent-2.0.19-1.rhel6.x86_64 (pgdg94)
               Not found
           Available: libevent-1.4.13-1.el6.x86_64
(rhui-REGION-rhel-server-releases)
               libevent-1.4.so.2()(64bit)

Full log attached.

It looks like the libevent in PGDG for 9.4/EL-6 conflicts with that in
RHEL6, and should instead install in parallel to it as a "libevent2"
with a different soname.

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