why "order by" and "like" doesnt work in 7.3.4 properly? - im working
with ALT server local settings.
in 7.2.xx all this things worked well .

Most likely you forgot to select the right locale settings before
initdb'ing the 7.3 installation. pg_controldata can help you check
what locale is in force in the database.

Thank u for hint it really helped me - I made initdb with new lc-ctype
and lc-collate
settings : ru_RU:UTF8.
But im having one question - some functions - lower() and upper()
doesnt work properly . what im doing wrong?

We don't have any support for upper() and lower() in multibyte character
encodings, such as UTF8. You need to use a single-byte encoding (and a
locale setting to match, of course).

Yeah, I know this sucks :-(. I think Peter Eisentraut is looking into
fixing it for 7.5.
