Description: DISTINCT fails with national character varying
Details:
create table depression(ID int, name national character varying(50))
insert into depression values(1, 'Ана');
insert into depression values(2, 'Ива');
insert into depression values(3, 'Ина');
insert into depression values(4, 'Яна');
select distinct name from depression
--the last statement returns only a single row
--namely: Ана
--it should return 4 rows!

This has been seen to happen when you select a database encoding that
does not match the encoding expected by the postmaster's LC_CTYPE locale
setting. It's really a bug in the locale definitions, if you ask me,
but good luck getting the glibc guys to change those :-(. In the
meantime, make sure your locale and encoding agree.

Thanks, Tom!
I'll tackle this issue this weekend.
I'll also upgrade to PostgreSQL 8 (most probably)
Thanks once again for your comprehensive reply!
Best regards,
Ludmil Tinkov
