How to turn off url aliases on dev site? I'm using path auto to automatically generate url aliases. On my dev site it would be convenient to use standard node/123 urls. 
Is there a way to do that? Just turning off pathauto and path won't do the trick
I think the problem is that the {url_alias} still has the aliases in it.

My suggestion would be to take a backup, then delete a few manually from "admin/build/path" (Drupal 6) or "admin/config/search/path" (Drupal 7), and then try the "node/nid" paths for the entries you deleted.  Then, take another backup :) and either delete them via the Delete aliases tab.
