alexander,
lc_ctype and lc_collate can be changed only at initdb !
You need to read localization chapter
http://www.postgresql.org/docs/current/static/charset.html
Yes, i knew about this, but i thought maybe somehow it can be changed
onthefly.
... (10 minutes later)
Yes, now when initdb done with --locale=ru_RU.UTF-8, lower('RussianString')
gives me 'russianstring', though, case-insensiive regexp still not working. I
confirmed, checked with --locale=ru_RU.UTF-8 and 8.2.4,CVS HEAD.
No problem with --locale ru_RU.KOI8-R
guess i'll stick with lower() ~ lower() construction.
And thanks everybody who replied!

russian unicode characters,
In that case you're using the wrong locale (ie, not russian unicode).
Check "show lc_ctype".
db=> SHOW LC_CTYPE;
lc_ctype

db=> SHOW LC_COLLATE;
lc_collate

Where can i change this? Trying to SET this parameters gives error
"parameter "lc_collate" cannot be changed"
Or [ checks back in thread... ] maybe you're using the wrong operating
system. Not so long ago FreeBSD didn't have Unicode locale support at
all; I'm not sure if 6.2 has that problem but it is worth checking.
Does it work for you to do case-insensitive russian comparisons in
"grep", for instance?
I put to textfile 3 russian strings with different case of first char and
grep'ed them all:
# cat > textfile
Зеленая
Зеленодольская
зеленая
# grep -i зелен *
textfile:Зеленая
textfile:Зеленодольская
textfile:зеленая
So i think system is fine about unicode.

Oleg
