Well, I used the very same command with 8.0.3 to create a database,
and the sort order was correct:

--8<---------------cut here---------------start------------->8---
scratch=# select w from w order by w;
w
-------------
Abend
Oma
Österreich
Überflieger
Unter
Zetrix
(6 rows)
--8<---------------cut here---------------end--------------->8---

So I guess there was some misconfiguration of your current
client_encoding during import, or maybe the dump of your unicode db
got unexpectedly converted by improper settings during dumping.

The sort order is correct, so libc did succeed in its part. Maybe your
terminal is having issues with utf-8? If you're using xterm: Did you
run it with -u8 or some utf-8-enabling X-resource? To verify that the
terminal is working properly, typing

echo ö > /tmp/foo
file /tmp/foo

on a shell should tell you that you have a utf-8 text file.
