WIN1251 localization - Mailing list pgsql-general

Hello, All !

I am developing database. Initial scripts contains information in win1251 encoding. Now I have received problem

c_db1=# \encoding WIN1251

WIN1251: invalid encoding name or conversion procedure not found

c_db1=# 

locale in system was defined by this

$ sudo localedef -c -i ru_RU -f CP1251 ru_RU.CP1251

$locale -a | grep ru

ru_RU.cp1251

ru_RU.utf8

ru_UA.utf8

system ubuntu linux 11.10, where is an error and how to correct this ?
