Maybe an additional test like "(executable-find
doc-view-ghostscript-program)" would be useful here.

I agree.  And it should accept an argument TYPE (`postscript', `pdf',
`dvi') like `image-type-available-p' to decide it for each document
type, e.g. ...

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

Bye, Reiner.
