Is this really a good idea? I think the clustering itself should be
done later and manually by the DBA, and the dump should only include a
command to set the indisclustered bit appropiately. What about
inventing a command to only set the bit, maybe
ALTER TABLE <tablename> CLUSTER ON <indexname>
or something like that? I can do that if people thinks it's a good
idea.
