One other thing that I just thought of. I think it is actually possible
to add an index on a function of a column. So if you have the
"is_really_pending" function, you might be able to do:
CREATE INDEX pkk_is_really_pending ON pkk_purchase
(is_really_pending(purchase_id));
But you need a better guru than I to make sure of that.
This *might* do what you need.
