Yeah. Also, as you noted, we could mark some individual built-in
variables as SUSET and add a default GRANT. I don't want to do that with
a blunderbuss, but perhaps there's an argument to do it for specific
cases (search_path comes to mind, though the performance cost could be
significant, since I think setting that in function SET clauses is
common).
For now, though, saying that you can't restrict SET for USERSET variables
seems fine --- there's certainly no loss of capability compared to where
we stand today. I'd prefer to get the feature committed in that form
and then look at whether we want to tighten things around the margins.
