Yeah, I'd meant to bring that up too. The ability to use ALTER
SYSTEM freely is probably a much bigger use-case than messing with
SUSET variables within one's own session.

I'm still of the opinion that slicing and dicing this at the per-GUC
level is a huge waste of effort. Just invent one role that lets
grantees set any GUC, document it as being superuser-equivalent,
and be done.
