Sure, but then you do "\dconfig *". With there being several hundred
GUCs (and no doubt more coming), I'm not sure that "show me every GUC"
is a common use-case at all, let alone so common as to deserve being
the default behavior.
One thing we could perhaps do to reduce confusion is to change the
table heading when doing this, say from "List of configuration parameters"
to "List of non-default configuration parameters".
