So, now after setting it so high and seeing the above output, we ran vacuum
verbose again today to check it and it looks like this now:

CPU 0.00s/0.00u sec elapsed 0.00 sec.
INFO:  free space map contains 27804 pages in 125 relations
DETAIL:  A total of 29600 page slots are in use (including overhead).
29600 page slots are required to track all free space.
Current limits are:  3366499 page slots, 2000 relations, using 19853 KB.

What the heck?  Why would it have shrunk down so much?  The vacuum full isn't
scheduled until tonight. :-/
