Incorrect solution: install win1251 locale. Once I saw a reference to
such beast in Russian Apache mailing list. Search through mail archive,
look into Apache-Rus FAQs...

Correct solution: use koi8-r locale and koi8<=>win1251 on-the-fly
conversion. Postgres starting from 6.5 can do on the fly conversion between
many Cyrillic locales. Look into doc/README.locale.
