Well, my point is that that is a larger assumption about the behavior of
pg_bind_textdomain_codeset() than I think we ought to make, even if it
happens to be true today.

I'm not exactly sure that they wouldn't be garbled anyway during the
interval where we're setting these things up. Until DatabaseEncoding,
ClientEncoding, and gettext's internal notions are all in sync, we
are at risk of that type of issue no matter what.
