Hmm, no.  FOR UPDATE OF isn't a postgres extension, but a part SQL which mysql
doesn't implement fully (SQL:2003 14.1.).

But yeah, trying to lock on an outer join is fundamentally nonsensical, and
mysql not throwing an exception is a standard compliance bug at best - it's
unwise to rely on that kind of behaviour.
