Yes, I've just discovered the Todo list :) Oh well, it probably
needed rethinking anyway.....I want fast retrieval over fast
update so I probably want to do my min() and max() magic with
triggers on insert/update/delete rather than on each select
with the view.
In any case I have attached some SQL which sets up tables and
generates the ExecEvalAggref I was getting in case it is of
any use to anyone.
Cheers.
