Why not? Undoing whatever you did to the locale setup seems a lot
easier task than any other option that's open to you.
I would *not* recommend hand-editing pg_control, even if you got the
CRC correct. There is a reason why we put in code to prevent on-the-fly
changes of locale: it corrupts your indexes. You might be able to get
the postmaster to start, but that wouldn't mean you could trust the
output of pg_dump.
