... unless the function is a SQL function that is trivial enough for the
planner to inline it into the plan of the invoking query. Currently, we
won't inline set-returning SQL functions that are used in the query's
rangetable, though. This would be worth doing, I think -- I'm not sure
how much work it would be, though.
