+1 for this solution.
BTW, there was some mention of changing the timestamp versions of
generate_series as well, but right offhand I'm not convinced that
those need any change. I think you'll get overflow detection there
automatically from the functions being used --- and if not, it's a
bug in those functions, not in generate_series.
