No, it won't. See docstring for `org-export-with-drawers'. Property
drawers are very different from regular drawers.

Through macros, you can already access to specific properties, e.g.:

  {{{property(ARCHIVE)}}}

There is no function to dump the whole database in the export buffer
because it contains many Org-specific entries which are irrelevant and
because there are many ways to dump it.

That's not what you asked, but the following function:

#+begin_emacs-lisp
(defun my-database-dump (backend)
  (goto-char (point-min))
  (while (re-search-forward "^[ \t]*:PROPERTIES" nil t)
    (let ((element (org-element-at-point)))
      (when (eq (org-element-type element) 'property-drawer)
        (goto-char (org-element-property :end element))
        (insert "#+BEGIN_EXAMPLE\n"
                (buffer-substring (org-element-property :begin element)
                                  (progn (goto-char
                                          (org-element-property :end element))
                                         (skip-chars-backward " \r\t\n")
                                         (forward-line)
                                         (point)))
                "#+END_EXAMPLE\n")))))
#+end_emacs-lisp

when added to `org-export-before-parsing-hook', will wrap every property
drawer within an example block so it can appear in the export output.
