I don't buy this at all. What's going to be terribly confusing is to
have config changes start happening for users who are managing their
configs through a CM (which most should be..). ALTER SYSTEM is going to
cause more problems than it solves.

That's really a horrible, horrible answer. The DBA makes some change
and then reloads remotely, only to have puppet or chef come along and
change it back later? Talk about a recipe for disaster.
The only reason I stopped worrying about the foolishness of ALTER SYSTEM
was because it could be disabled. I'm very disappointed to hear that
someone saw fit to remove that. I'll also predict that it'll be going
back in for 9.5.
Thanks,
