Update to pg9.4.12 failing with Error: Cannot find a valid baseurl for repo

Running into 'invalid release' error when trying to update postgres to the
latest minor version 9.4.12 on CentOS 5.11:

sudo yum update postgresql94.x86_64 postgresql94-contrib.x86_64
postgresql94-devel.x86_64 postgresql94-libs.x86_64
postgresql94-server.x86_64

removing mirrorlist with no valid mirrors:

Error: Cannot find a valid baseurl for repo: base

Downloaded the rpm from
https://download.postgresql.org/pub/repos/yum/9.4/redhat/rhel-5-x86_64/pgdg-centos94-9.4-3.noarch.rpm
but still getting the same error when trying to install it:

:/etc/yum.repos.d> yum --nogpgcheck localinstall

Since 9.4.12 yum package is listed at
https://yum.postgresql.org/repopackages.php I think it means support for it
has not dropped. Not sure why I am seeing this error then.
