You should have a look at this How I can delete all node/field revisions?, and perhaps subscribe to http://drupal.org/node/1063266#comment-5268252

Is it safe to truncate a field revision table?
I want to create an app/package to be published on the appexchange.  The only functionality of that app/package will be to redirect the user to a configured URL in the app. This will happen once enterprise admin adds the app from the appexchange.

The redirect functionality is related to remote access via Oauth2. Once redirected to the URL, the URL endpoint will kick in and do all the further steps.

I do NOT want the admin of the enterprise to make any config e.g creating webtab or a link as a workaround to making some package. This SHOULD be done when the app is added.

In other words, can we make an app that does not contain any tab, but just a URL?

Also, Can we package remote access apps?
