Since the entire point of having those views is to have a standard-conformant way of accessing the information in the system catalogs, adding nonstandard columns would rather defeat the purpose. If you can persuade the relevant ISO standards committee that this is a good idea, we will adopt the change when it appears in a published version of that standard --- otherwise, it seems quite unlikely that we'd accept a change to the view definition. You'd probably be better off to define your own nonstandard view, IMO. regards, tom lane
