PostgreSQL version: 8.1.4
Operating system: win2000
Description: Incorrect ILIKE, ~* for Cyrilic symbols.
Details:

Microsoft Windows 2000 [Version 5.00.2195]
PosgreSql 8.1.4
PgAdmin 1.4.2 III
for Cyrilis symbols ~* and ILIKE return wrong result
data base is created by:
initdb.exe -E UTF8 --lc-collate=UTF8 --lc-ctype=UTF8 "c:\Program
Files\PostgreSQL\8.1\basewin1251\"

then...
postmaster.exe -D "c:\Program Files\PostgreSQL\8.1\basewin1251\"
then
connect to server on local w PgAdmin 1.4.2 III
I see db:

CREATE DATABASE postgres
WITH OWNER = postgres
ENCODING = 'UTF8'
TABLESPACE = pg_default;

Go to SQL Query
SELECT upper('ПроБа ЇїЄєІі'), lower('ПроБа ЇїЄєІі'),
'Ї'ILIKE'ї'

return incorrect FALSE for last ILIKE
It must be TRUE
