I don't think I trust this idea, and in any case it doesn't remove
all the overflow hazards: the reduction of the stride interval to
microseconds can overflow, and the final subtraction of the stride
can too.  I changed it to just do the straightforward thing
(throwing error if the pg_xxx_s64_overflow routines detect error),
and pushed it.  Thanks for the report and patch!
