... and the reason we don't emit a HINT here is that the exact same
HINT would apply in any context involving identifiers, so we'd just
flood the logs. It'd be spurious in most cases.

We could only emit a useful HINT if we actually went and looked in the
relevant catalog for a different-cased version. Which is pretty
expensive.
