As committed, it prints anything that's shown as "source != 'default'"
in pg_settings, which means anything for which the value wasn't
taken from the wired-in default. I suppose an alternative definition
could be "setting != boot_val". Not really sure if that's better.
This idea does somewhat address my unhappiness upthread about printing
values with source = 'internal', but I see that it gets confused by
some GUCs with custom show hooks, like unix_socket_permissions.
Maybe it needs to be "source != 'default' AND setting != boot_val"?
