Can we also update this wording:

INFO:  free space map: 52 relations, 61 pages stored; 848 total pages needed
DETAIL:  Allocated FSM size: 1000 relations + 20000 pages = 182 kB shared memory.

The "pages needed" is confusing.  In fact it is the total pages used or
allocated.  I looked in the code and got confused.  It needs clarity.
Right now it sounds like you need more when you don't.
