Thanks. It would've been easier if you'd provided a more concrete test
procedure, but I've been able to reproduce what seems to be the same
failure. I don't know exactly what to do about it yet :-( --- see

At the moment it appears to me that this error could only occur in
CLUSTER or its close cousin VACUUM FULL; ordinary database queries could
not see such a failure. Does that agree with your experience? If so,
this isn't really a data loss bug, so you should be able to just live
with it until we can work out a fix.
