upgrading to 8.3, utf-8 and latin2 locale problem

Hello,

I am sure this won't be the first e-mail about this issue, however we
are upgrading production-like environment. Please help.

For reproducing I've used two debian servers, same locales (en_US.UTF-8,
en_US ISO-8859-1, hu_HU.UTF-8, hu_HU ISO-8859-2), Debian testing.

------------------------------------------------
Postgresql 8.2 (8.2.6-2):

/usr/lib/postgresql/8.2/bin/initdb -D /home/readonly/pg_data/
--locale='en_US.UTF-8' --lc-collate='hu_HU.UTF-8'
--lc-ctype='hu_HU.UTF-8' --lc-time='hu_HU.UTF-8'
The files belonging to this database system will be owned by user "mage".
This user must also own the server process.

The database cluster will be initialized with locales
COLLATE: hu_HU.UTF-8
CTYPE: hu_HU.UTF-8
MESSAGES: en_US.UTF-8
MONETARY: en_US.UTF-8
NUMERIC: en_US.UTF-8
TIME: hu_HU.UTF-8
The default database encoding has accordingly been set to UTF8.

/usr/lib/postgresql/8.2/bin/pg_ctl -D /home/readonly/pg_data -l logfile
-o '-p 5555' start
/usr/lib/postgresql/8.2/bin/psql -p 5555 template1

# create database test encoding = 'latin2';
CREATE DATABASE

------------------------------------------------
Postgresql 8.3 (8.3.0-1):

/usr/lib/postgresql/8.3/bin/initdb -D /home/readonly/pg_data/
--locale='en_US.UTF-8' --lc-collate='hu_HU.UTF-8'
--lc-ctype='hu_HU.UTF-8' --lc-time='hu_HU.UTF-8'
The files belonging to this database system will be owned by user "mage".
This user must also own the server process.

The database cluster will be initialized with locales
COLLATE: hu_HU.UTF-8
CTYPE: hu_HU.UTF-8
MESSAGES: en_US.UTF-8
MONETARY: en_US.UTF-8
NUMERIC: en_US.UTF-8
TIME: hu_HU.UTF-8
The default database encoding has accordingly been set to UTF8.
The default text search configuration will be set to "hungarian".

/usr/lib/postgresql/8.3/bin/pg_ctl -D /home/readonly/pg_data -l logfile
-o '-p 5555' start
/usr/lib/postgresql/8.3/bin/psql -p 5555 template1

template1=# create database test encoding = 'latin2';
ERROR: encoding LATIN2 does not match server's locale hu_HU.UTF-8
DETAIL: The server's LC_CTYPE setting requires encoding UTF8.

In Google we've found similar err messages for pg_upgradecluster.

----------------

Both server:
show all;
client_encoding | UTF8
lc_collate | hu_HU.UTF-8
lc_ctype | hu_HU.UTF-8
lc_messages | en_US.UTF-8
lc_monetary | en_US.UTF-8
lc_numeric | en_US.UTF-8
lc_time | hu_HU.UTF-8
server_encoding | UTF8

We would like to upgrade from 8.1 to 8.3. We have UTF-8 and LATIN2
databases. Any idea?
