Vacuum info clarification
The last two lines of VACUUM VERBOSE are:
INFO: free space map: 49 relations, 32 pages stored; 784 total pages needed
DETAIL: Allocated FSM size: 1000 relations + 20000 pages = 182 kB shared memory.
I think "total pages needed" should be "total pages used" or "total
pages requested".
I am confused about the difference between "stored" and "requested". I
read the comments in freespace.c but am still confused.
