I remember someone proposed a patch for that a long time ago:
http://archives.postgresql.org/pgsql-patches/2006-10/msg00154.php
AFAICS there were 2 possible follow-ups to this patch:
- only manage the case of char/varchar (which is the most common case anyway);
- develop a complete infrastructure to handle all the cases as
suggested by Gregory.
