Not necessary, since the freespace map will never be large enough to
overflow a signed int (it wouldn't fit in the address space if it were).
I think that your changes in vacuum.c are probably unnecessary for the
same reason. I am generally wary of changing values from signed to
unsigned without close analysis of how they are used --- did you look
at *every* comparison involving these fields? How about arithmetic
that might compute a negative result?
