PostgreSQL version: 8.0.4
Operating system:   RHES
Description:        ERROR:  invalid multibyte character for locale
Details:

Hello,

Got the error in postgres console when we do a lower() or upper().

Postgres console gives following error,

ERROR:  invalid multibyte character for locale
HINT:  The server's LC_CTYPE locale is probably incompatible with the
database encoding.

Can any one please help me, I need to use Unicode encoding for my database.
(Not able to upgrade to postgres 8.10. as I was getting someother issues
when I try to restore  database)

Looks forward for anyone's fast reply.

Thanks,
Prakash
