There is an exception that will allow superusers to do that, but it's
not a good idea for them either.  The problem is not the encoding per
se, it's that it's unsafe in combination with a locale setting that
assumes UTF8.  The only safe locale for SQL_ASCII is C.

If you want to have one database that is C/SQL_ASCII and others that
have different locale settings, you need to upgrade to PG 8.4.  8.3
can only have one locale across the entire installation.
