Doesn't anyone know if I could override this settings?
LC_COLLATE should be interesting for sort order, and while both is utf8,
it should work or am I totally wrong?

As far as I read right now, LC_COLLATE is a read_only variable which is
used while initdb. But why does the pg_upgrade script doesn't see that
utf8 and UTF-8 are the same? Is it just a string compare?
