Would be interesting as a parameter to set at index creation (ie. if you know this table will have a lot of reads and few writes)... like create an index on columns X,Y keeping data on columns X,Y and Z... But in this case do you still need the table ? Or even create a table type where the table and the index are one, like an auto-clustered table... I don't know if it would be used that often, though ;)
