Thanks, I think this is good to go, except that I think we need to use
pow() rather than powl() because AIUI powl() is new to C99, and so
won't necessarily be available on all supported platforms. I don't
think we need worry about loss of precision, since that would only be
an issue if rel->rows / rel->tuples were smaller than maybe 10^-14 or
so, and it seems unlikely we'll get anywhere near that any time soon.

I think this is a good, well thought-out change, so unless anyone
objects I'll push it (probably this weekend).
