      Use mul_size when multiplying by the number of parallel workers. · 06bd458c
      Robert Haas authored 
      That way, if the result overflows size_t, you'll get an error instead
of undefined behavior, which seems like a plus.  This also has the
effect of casting the number of workers from int to Size, which is
better because it's harder to overflow int than size_t.

Dilip Kumar reported this issue and provided a patch upon which this
patch is based, but his version did use mul_size.
