You don't have max_fsm_pages set large enough. Note the output at the
end of the VACUUM printout:
> INFO: free space map: 67 relations, 20713 pages stored; 29872 total pages needed
> ��������: Allocated FSM size: 1000 relations + 20000 pages = 186 kB shared memory.
30000 instead of 20000 would be enough at the moment, but I'd suggest
going to 100000 to give yourself some breathing room.
