Hi David,

    I have a question that is a specification of permission check
    (visibilityrule) for psql meta-command with schema option.

Visibility means search_path, not permission.  If s_a is not in the 
search_paths it objects are not visible unqualified but can be seen (catalog) 
when schema qualified.

Thanks for your comments! I understood them:
 - all users can show System catalog (pg_catalog. *) is a
   specification, so it is not a bug
 - visibility and permission are not the same (I confused it before, oops)

Regards,
Tatsuro Yamada
