You know what's funny about this article.... Back in 2012 I had the same problems with Windows Update and that is what forced me to go to a mac. I've never looked back.
After setting up numerous clusters with repmgr and patroni along with running them in zero down time production... This is the very last plugin i would ever install. I like to sleep at night.
