Is there any way to use doc-view to open PDF at specific page number?
I know there is function doc-view-goto-page, I would like to open PDF
file at specific page number.

(add-hook 'doc-view-mode-hook (lambda () (doc-view-goto-page 10)))
will open *every* PDF file at page 10 (not sure what happens if
there is no page 10), but I presume you will want to make it
interactive. So you can write a function that asks for the page
number, and adds something like this to the doc-view-mode-hook,
after cleaning up any previous such setting. Then add it as a -before
advice to find-file.
I tested the hook setting but not the rest of it: caveat emptor.

Scratch that - you'd hardly want to be asked another question every
time you call find-file. Maybe the thing to do is to add the function
to find-file-hook, but I thiink by that time the mode function has
been executed already, so the doc-view-mode-hook will not be run. But
maybe you can call doc-view-goto-page directly.
