FROM ... ) I don't know whether the planner is smart enough to optimize on "= ANY()" - whether statically generated or determined at runtime. I am pretty sure that constraint exclusion must be done during the planning stages and that you have to pass in a literal set of values (or an array) that you generate in a previous query.
