Re: BUG #3737: lower/upper fails to match extended chars in LATIN1

From my point of view (administrators view, not developers) it is such
a drawback
in postgres implementation that it seriously challenges the position as
a competitor
to the big dragons. (IF they suffer from the same missing feature)

Recreating indicies is maybe not great but can be done quit easily compared
to reinitializing a db or recoding an entire database.
Sometimes a bit of a solution is all what it is needed. Would it be possible
to change the locale on the fly and only recreate indicies afterwards?

ps. I'd love to send you a patch, but there is no way it would be a good
thing
time/performance wise for me doing this. I am trying to be a great
ambassador though,
spreading the words everywhere. ds.
