Are we agreed that the TRUNCATE-based workaround shown here
http://archives.postgresql.org/pgsql-hackers/2007-03/msg00606.php
is an adequate response to this objection?

(This assumes of course that TRUNCATE will never become MVCC-safe,
but I think that's a reasonable thing to assume.  I notice we don't
document TRUNCATE as unsafe ... will go fix that.)
