Collation support was tightened in 8.4; a lot of users are affected by
similar problems. Technically, you shouldn't have used a KOI8U locale
in 8.2 to begin with, because that encoding wasn't supported by
PostgreSQL back then. Only that 8.2 didn't check that.
It would be fairly simple to create conversion support between KOI8R and
KOI8U, if you would like to look into that.
