Years ago there was some experimentation with dump-rate throttling logic
inside pg_dump itself --- there's still a comment about it in pg_dump.c.
The experiment didn't seem very successful, which is why it never got to
be a permanent feature.  I'm curious to know why this perl script is
doing a better job than we were able to do inside pg_dump.
