Hm, apparently you changed the system-wide language setting between F21
and F22?
One thing you should do is file a bug in Red Hat's bugzilla, pointing out
that postgresql-setup needs to endeavor to create the new cluster with
lc_collate and lc_ctype matching the old one.
Then, depending on what you want to do:
1. You really want to switch to en_AU, not just system-wide but for the
database: gonna have to dump and reload, I'm afraid. pg_upgrade will
not handle this scenario.
2. You want to switch to en_AU system-wide but it's okay to leave the
database running in en_US: what I'd do personally is edit the
postgresql-setup shell script and add "export LANG=en_US.UTF-8" just
before the initdb call. This won't stick across your next Fedora
upgrade, but hopefully by then Red Hat will have addressed your bug.
3. This was a mistake and you'd rather stay in en_US all round:
you can probably change the system-wide language setting somewhere,
but I do not remember where right at the moment.
