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.
