There are some misunderstood. Im using Linux 2.6.16.4, postgresql 8.1.4,
(there are one of locale: lv_LV.utf8, for Latvian language). But if I
want do "lower", then with standard latin symbols all is ok, but with
others special symbols (like umlaut in Germany) there is problems, and
sorting is going not like alphabet but like latin alphabet and specials
symbols after. :(

For sorting there are solution function nls_to_string(), witch is using
C library and system locales for converting strings to binary. But it
dont work for search (like, tsearch2, e.c.)

I dont know what to do, but function lower() is not working for special
symbols (LATIN 7).

And I tried in windows - the same... (as I know windows knows how to
converts latvian symbols lower, upper... in UTF-8)...
