I seem to recall that at some point in the distant past, somehow some
Linux distributions changed the canonical spelling of locale names from
xx_YY.UTF-8 to xx_YY.utf8. So if people are upgrading old PostgreSQL
instances that use the old spelling, pg_upgrade will probably fail. A
fix might be to take the locale name you find in pg_control and run it
through setlocale() to get the new canonical name.
