RES: Issue on Varchar Ordering

Peter,

Thanks for answering.

But it's not correct to my language pt_BR and it worked correctly with
PostgreSQL at Windows and FreeBSD. I have this problem only with Debian and
now I'm looking for some Debian related issue.

That is, for practical purposes, correct.

May I suggest that you properly normalize your tables, by putting given
name and family name into separate columns.
