problem with nasty latin2 sorting

What's wrong? Is there any patch to fix this? Does anybody had similar problem?
I belive that postgres was compiled with "--enable-locale", and the right
locale is set.

What does "show lc_collate" say?
What does \l show in psql?

what do you get on your machine if you save that same list in a file and run
"sort" on it on the commandline set (with LC_COLLATE set to the same value as
above)?

How sure are you of that? This sure sounds like a wrong-locale problem
to me. Try "show lc_collate" and "show server_encoding".

For example, I've got couple of polish cities in my table 'x',
results of sorting are:
(select city from x order by city asc)

Bydgoszcz
Gda?sk
I?awa
?�d?
?arn�w
Malbork
Warszawa

So "?arn�w" is placed in wrong place, because it should be found
after letter "Z" ??

Beside previous suggestions, I'm curious about your libc version too.
PostgreSQL relies on system locale while making character related
processes - like case conversion, collation and etc. Does below
command set succeed in sorting above data:

$ export LC_COLLATE=<related_locale>
$ cat >/tmp/test.out <<EOF

Bydgoszcz
Gda...
...
EOF

$ sort /tmp/test.out

If above command set doesn't succeed, this means your problem is with
libc. Otherwise, as mentioned in the previous posts, please check your
database encoding.

Regards.
