Does this reorganizing refer to what we do with CLUSTER ? I'd really love to be able to CLUSTER a table with ALLOW WRITE ACCESS. currently this requires quite a complicated dance with views,triggers, logfiles and changing access funtions. > They actually support three modes: > > ALLOW NO ACCESS > ALLOW READ ACCESS > ALLOW WRITE ACCESS > > I'm not sure where that leaves us.
