I think what Reini was asking was why do you think you need bitmap
indexes as opposed to any existing type?

due to I'm developing a datawarehousing application we have lots of fact-data in our central fact-table. As I know how to improve performance on Oracle based datawarehouses, I'm used to add bitmap indexes for atributes having only a few distinct values. So I was looking for any comparable indexing technology but didn't find any so far.

Yann, you may try our contrib/intarray module
