and are they all in a 3.5 cluster?
Your priority should be to get them to 3.6 compatibility prior upgrading to 4.0, then once in 4.0.3+ there is a safe-enough way how to properly update 3.6 to a 4.0 cluster level.

otherwise, any <3.6.7 would allow you to do that or there is a manual postgres workaround mentioned in that bug which you can try/risk - basically as long as you can reboot those VMs in a foreseeable future(prior to use any of the new features) you can follow the manual workaround and upgrade to 3.6….just make sure you stop and start them eventually

Please shutdown all VMs in the Cluster.” According tohttps://bugzilla.redhat.com/show_bug.cgi?id=1341023 <https://bugzilla.redhat.com/show_bug.cgi?id=1341023> this should be fixed in 3.6.7. Any ideas?
