I think that's already on the roadmap --- it's one of the reasons we
ended up with a SELECT-like syntax for CREATE STATISTICS. But it
didn't get done for v10.
If we do look at that as a substitute for "make an expression index just
so you get some stats", it would be good to have a way to specify that you
only want the standard ANALYZE stats on that value and not the extended
ones.
