Yes, it seems this is just a matter of adding

     ("application/postscript"
      (viewer . doc-view-mode)
      (test   . (fboundp 'doc-view-mode))
      (type   . "application/postscript"))
     ("application/pdf"
      (viewer . doc-view-mode)
      (test   . (fboundp 'doc-view-mode))
      (type   . "application/pdf"))
     ("application/dvi"
      (viewer . doc-view-mode)
      (test   . (fboundp 'doc-view-mode))
      (type   . "application/dvi"))

to `mailcap-mime-data'.

I agree.
