If clarity is the goal, I'd want the following:

a) Verbosely spelling out the units in the default config file
   temp_buffers = 16 megabytes   or   temp_buffers = 16 milliblocks :-)
   Naive users who favor cut&paste will use the verbose words   that should leave little room for confusion.
Power-users  who know the short forms from the docs will presumably have   read the descriptions.
 

b) having "show" show verbosely spelled out units.   db=# show temp_buffers;   temp_buffers   --------------   16000000
bytes  (1 row)
 

c) having "set" show a NOTICE with the verbose word for the units  db=# set temp_buffers = '16mb';  NOTICE: setting
temp_buffersto 16000000 bytes
