As Devrim  blogged about  Postgres YUM repo changes , I wanted to write down procedure I have to follow this morning  

For example,

If you want to update YUM repo for Postgres 9.4 on CentOS x86_64, you can update executing below command:

yum localinstall https://download.postgresql.org/pub/repos/yum/9.4/redhat/rhel-6-x86_64/pgdg-centos94-9.4-3.noarch.rpm

Now,  you can follow normal Postgres version upgrade procedure.

Hats off to Devrim to build new packages and all the recent improvements in repo management process! He updated wiki page as well.

Hope this will help someone
