Hi! I just came across an interesting article in a german PC-Mag, covering use of universal B-trees for indexing multi-index databases. Looks VERY promising, indeed. I dunno if that could be implemented in postgreSQL, or is of any interest at all, but here's an URL for anyone ineterested: http://mistral.in.tum.de They have set up a nice web page showing the ins and outs of the algorithms, and nice presentations. As a plus, the results they had seem VERY good... Greetings, Joerg
