I looked into how easily this back-patched to v15 (where commit 88103567c
was added), and I noticed that the ALTER SYSTEM code looks a bit different
on v15 and v16.  Furthermore, I didn't see a simple way to fix it on those
versions without first back-patching commit 2d870b4.  From the commit
message, it looks like Tom didn't back-patch it at the time due to a lack
of complaints.  I'm currently thinking we should first back-patch that one
to at least v15, if not all supported versions, before applying my proposed
patch.  Thoughts?
