Hello,

I'm running Postgresql 7.3.4 with ru_RU.UTF-8 locale (with UNICODE
database encoding), and all is almost well, except that UPPER() and
LOWER() seem to ignore locale.

I searched the sources couple of times, but do not understand where is
the implementation of UPPER()/LOWER().  Could you please point me to
the right direction?

I'll try to understand and fix that.  (But maybe patches for that
exist?  Or maybe FreeBSD 4.8-RELEASE utf-8 locales are broken in that
respect?)


Thanks a lot,

--alexm
