Nowadays we are going to provide views for such files. Howerer I'm not a fan of checking extension packaging using such views, I agree that it's good to have at least a function/view that shows all available attributes of extensions. Is there no other items not in controlfiles? > Any opinion in adding a new view like "pg_available_extension_details" to > display all extension control file columns? or Adding them to the existing > view is good? I felt it's a bit too noisy at first but pg_settings is doing something like. So +1 to extend the existing pg_available_extensions view from me from the viewpoint of consistency with other views of the similar objective. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
