Several good suggestions have been made, like "summarizing" or
"summary" indexes and "compressed range" indexes. I still really
dislike the present name - you might think this is a type of index
that has something to do with optimizing "min" and "max", but what it
really is is a kind of small index for a big table. The current name
couldn't make that less clear.
