FYI, Works just fine on gentoo with the UTF8 and ICU patches.

What makes you think this is a Postgres bug, rather than a bug in the
locale definition you are using on the SUSE box? Try feeding the two
strings in question to strcoll() and see what happens.

One way that you can get inconsistent results from strcoll() is if you
feed it strings that are invalid according to the character set encoding
that strcoll() thinks you are using, which is to say the encoding
implied by the current LC_CTYPE locale setting. So it's possible that
the real problem is that you have Postgres' database encoding set to
something that's incompatible with the postmaster's LC_CTYPE locale.
(Try "show lc_ctype" to see what that is exactly.)
