This is probably more about dumping from different operating systems.
The spelling of the locale name is under the control of the OS,
and Postgres doesn't know very much about the semantics of it
(so I think we conservatively assume that any difference in
spelling is significant).
Best bet might be to edit the dump file to adjust the locale
spellings to match your new system.
