My initial concern when I first heard about this feature though was that this new flexibilty could be a very dangerous thing in the wrong hands. I can easily imagine databases all over place becoming over-indexed with numerious indexes on the same column list simply because you can with little thought. Should the index be a b-tree or a bitmap, unique or non-unique, partitioned or not, I know what, I’ll create 6 and play it safe :) If nothing else, the ORA-01408 offered some kinda protection from such “abuse”.
