Description:
Please consider adding support for an additional index type, bitmap indexes.

Oracle has a decent explanation on this index type at http://www.oracle.com/technology/pub/articles/sharma_indexes.html

Bitmap indexes would be very useful in a data warehouse environment when many rows will contain the same amount of data (for aggregation), unlike b-tree indexes which are good for unique column values.
