It's just text, no?  Are there any operations where this actually makes
a difference?

Like Robert, I'm *very* wary of trying to introduce any text storage
into the backend that is in an encoding different from server_encoding.
Even the best-case scenarios for that will involve multiple new places for
encoding conversion failures to happen.
