Hi,

I've been reading the FSM README file lately (src/backend/storage/freespace/README), and I'm puzzled by one of the graph (the binary tree structure of an FSM file). Here it is:

    4  
 4     2  
3 4   0 2    <- This level represents heap pages

Shouldn't the last line be:
4 3   2 0

(ie, highest number of free space on the left node, lowest on the right one)

Probably just nitpicking, but still, I'm wondering if I missed something out.

Thanks.
