Re: Cube extension improvement, GSoC

   * Learning cube extension to store dimensions with different data types. Such index would be good alternative to compound key B-Tree multi-index (suitable for diapason queries and data ordering).

You mean, a cube containing something else than floats? I don't think we want to explode the number of datatypes by doing that, casting between them could be problematic.

But I wonder if you could add cube-like operators for arrays. We already have support for arrays of any datatype, and any number of dimensions. That seems awfully lot like what the cube extension does.
