In the future we may get lazy evaluation of functions. When and if that
happens we may want to remove this limitation so that you can get a
streaming result producing timestamp values continuously.

(I don't necessarily think you'd use generate_series in such cases.
Maybe you'd want clock_timestamp to generate the present value at each
call, for example. But there may be uses for synthetic values as well.)
