PostgreSQL version: 9.6beta3
Operating system: RHEL 6.8
Description:
Steps to repro:
1) Install
http://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-redhat96-9.6-1.noarch.rpm
2) /etc/yum.repos.d/pgdg-96-redhat.repo shows
baseurl=[redacted]/rhel-$releasever-$basearch
yum-debug-dump shows that $releasever evaluates to '6Server' on RHEL 6.8,
which doesn't exist on the PGSQL mirror. Changing it manually to '6'
(baseurl=[redacted]/rhel-6-$basearch) corrects the problem and allows
packages to be installed.
