Another point worth mentioning is that one sometimes want to create indexes with physical details like PCTFREE, CLUSTER etc. Atleast DB2 complains that it will not create an index for you, if there already is an index on the same columns. Perhaps a DB or DBMS cfg parameter that determined whether index are auto created or not would be nice.
