That's the output of current_setting(name) which shows what it is right 
now; no more, no less.  See 
http://www.postgresql.org/docs/current/interactive/sql-show.html and 
http://www.postgresql.org/docs/current/interactive/functions-admin.html

That shows the parameter as the admin/usr set it, whereas the "setting" 
column in pg_settings displays in terms of the internal units.  Example 
session showing how that all fits together:

pg=# select current_setting('work_mem'); current_setting
----------------- 1GB
(1 row)

pg=# set work_mem='256MB';
SET

pg=# select current_setting('work_mem'); current_setting
----------------- 256MB
(1 row)

pg=# select setting,unit from pg_settings where name='work_mem'; setting | unit
---------+------ 262144  | kB
(1 row)

Since the word "current" isn't actually in the patch anywhere, and only 
appears in that little sample usage snippet I provided, whether or not 
it's a good name for that doesn't impact the patch itself.
