SHOW ALL doesn't actually SHOW ALL

Folks,

I've noticed that neither SHOW ALL nor SELECT ... FROM pg_settings
shows the value of custom GUCs, even though SHOW will do so for any
given one. For example:

SHOW plperl.use_strict;
plperl.use_strict
-------------------
true
(1 row)

SELECT * FROM pg_settings WHERE "name" = 'plperl.use_strict';
name | setting | unit | category | short_desc | extra_desc | context | vartype | source | min_val | max_val
------+---------+------+----------+------------+------------+---------+---------+--------+---------+---------
(0 rows)

Is this a bug?

Cheers,
David.
