LATIN2 'bssz' and 'bszsz' fails on unique index

Hello,

If you use Latin2 encoding, you can not have 'bssz' and 'bszsz' in an
unique column in the same time.

Is this  a known bug? Do you have any solution? (I use Latin2 encoding,
because I want to order by names, which contains accent characters.)

Welcome to psql 7.4.2, the PostgreSQL interactive terminal.

template1=# CREATE DATABASE test WITH ENCODING = 'LATIN2';
CREATE DATABASE
template1=# \c test
You are now connected to database "test".
test=# CREATE TABLE test (name character varying (128) UNIQUE NOT NULL);
NOTICE:  CREATE TABLE / UNIQUE will create implicit index
"test_name_key" for table "test"
CREATE TABLE
test=# INSERT INTO test (name) VALUES ('bssz');
INSERT 17798 1
test=# INSERT INTO test (name) VALUES ('bszsz');
ERROR:  duplicate key violates unique constraint "test_name_key"
test=#

I am running Debian Sid i386 with 2.6.6 kernel, libc6 2.3.2.ds1-12,
locales 2.3.2.ds1-12, postgresql 7.4.2-4 . Locale for postgres user is
"POSIX", locale for the psql client is "hu_HU". Both client and server
encoding for the above connections was Latin2.

Thanks,   d43m0n.
