that's just me again, here's normal patch for KOI8_U to

jdbc/Connection.java

Andy
P.S. in Connection.java if encoding=="WIN" then dbEncoding is set to
"Cp1252".
What if it's Cyrillic "WIN"? Than it should be "Cp1251". Is there any
way to fix that without making different "WIN" encodings in
PostgreSQL?
