    With this i just wanted to say that lower() doesn't work at all on
russian unicode characters, even in "select lower('String')" 'String'
don't become lowercase, and further it does not work in more complex
select statement.

     No, for russian unicode strings it is not working.
     I searched pgsql-patches@ list and found there this thread:
     http://archives.postgresql.org/pgsql-patches/2007-06/msg00021.php
     I wrote Andrew (he didn't answer yet) about whether this patch can
help with my problem.

P.S.: if this issue is a known bug (as we talked earlier), then how long
will it take to fix it? I know little about postgresql development
process, maybe you know it little better?
