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.
