The hyperlink syntax allows specifying a line number, however,

Is therea an extension to allow specifying a page number
so that a link to a pdf is opened at the specified page?
There is in the current git version, its not yet documented though.
Add an entry to the variable org-file-apps like this:
("\\.pdf::\\([0-9]+\\)\\'" . "evince \"%s\" -p %1")
Or as seen in the customize interface:
Extension: \.pdf::\([0-9]+\)\'
Command: evince "%s" -p %1
The subexpression \([0-9]+\) in the regex captures the page number,
which replaces the %1 in the command string. (This example assumes you
want to open your PDFs with evince, which accepts a page number after
the -p option.)
You can then reference a specific page of a PDF like this:
[[file:/path/to/document.pdf::42]]
I had planned to document this yesterday, but unfortunately spent the
better part of the day recovering from a cold. I will send a patch
describing how this works, when exactly the new behaviour kicks in and
the implications for backwards compatibility as soon as I find time to
describe it compactly enough to fit into the docstring.
