All:
One of the features for 9.5 will likely be "minmax" indexes, which are
indexes which index only the upper and lower bounds of each data page,
making for a very compact index ... like 100MB for a 100GB table.
The working name for these are "minmax" indexes which is not very
compelling and unlikely to reach users for how cool and useful they are.
Suggestions on an alternate name?
