Chaning bitmap-scan/or to roaringbitmap #1

Have you thought about it ? When joining multiple indexes, pg creates a bitmap for each and joins them. Changing it to roaringbitmap (less memory usage).

Not yet, it sounds like a good idea, I think this question can be sent to the pg mailing list to discuss
