I was joking about a rather magical automatic INDEX restriction
modifier. For example, if the index becomes large enough to matter
(100 Mbytes?) and any single key takes up more than, say, 20% of the
index, it might be cool if it would automatically add the value to
the restriction list, and prune the now wasted index records.
Sorry for inserting a silly joke in a serious discussion... :-)
Cheers,
