Hi,

Like the bug report that was submitted a few days ago,

http://archives.postgresql.org/pgsql-bugs/2005-09/msg00233.php

I have the same thing for Turkish locale. First I thought  that it was a
glibc error but glibc guys guided me here:

http://sourceware.org/bugzilla/long_list.cgi?buglist=1354

So it is PostgreSQL's bug or Glibc's?
