This is widely considered a security bug; read section 10 in RFC 3629 (the
definition of UTF8), and search the CVE database a bit if you still doubt
it's a threat. I'm going to push back very hard on any suggestion that
Postgres should build itself around a text representation with that kind
of weakness designed in.
