Has anyone else seen such a locale-based problem?

I would like to establish whether it is a problem in postgresql or in
libc.

   Works fine for me with 6.4 on 2 platforms:
   (Sun Solaris 2.5.1, locale=koi8-r (unix cyrillic))
   (x86 Debian 2.0, locale=koi8-r)

test=> create table test (name text, value int);
CREATE
test=> insert into test values('abc', 1);
INSERT 67895 1
test=> insert into test values('bca', 2);
INSERT 67896 1
test=> insert into test values('cab', 3);
INSERT 67897 1
test=> select name from test;
name
----
abc
bca
cab
(3 rows)

test=> select name from test where name like 'a%';
name
----
abc
(1 row)

test=> select * from test where name like 'a%';
name|value
----+-----
abc |    1
(1 row)

           Programmers don't die, they just GOSUB without RETURN.

Hi Oleg,

If I set the LANG variable to koi8-r or to any other values, then the
above select fails. :(

The system I use is a x86 Debian 2.1, it seems that this error has
something to do with libc6-2.0.7u, rather then postgresql.

Regards,
Tamas

   Debian 2.0 lacks koi8 locale - I have installed it manually. May be you
just have no proper localedata?
