It does. I think it works by just downcasing both strings. It's possible to do
better but tricky. I think 8.3 has an optimization for that for single-byte
encodings but it had to be disabled for utf-8 in the end.
If it's returning trash for those characters then it's not prepared to handle
UTF-8 data. You have to use an encoding compatible with your locale and
If you want to store UTF-8 data I suggest you
. add hu_HU.UTF-8 to /etc/locale.gen,
. rerun /usr/sbin/locale-gen
. pg_dump your database
. re-initdb with the locale set to hu_HU.UTF-8
. pg_restore your data.
Unfortunately that'll take quite a while and involve down-time.
You should probably do this in a second directory aside from your existing
database just in case you've created any invalidly encoded utf-8 strings.
You'll have to fix them before restoring. (Actually I don't recall which
version got strict about that.)
