In principle, yes, but in practice it's far more likely that operators
will have names requiring some sort of encoding than that objects with
SQL-identifier names will.

That's a good point.  However, I think that there are no cases where
we'd have dependencies between operators (or between casts), so that
as long as the initial sort is well-defined for them, it shouldn't
really be an issue in practice.
