Current product behavior results in emailed error message, primarily for field deletions. If fields are removed, an email comes in daily until user intervenes with these steps:

* Go to the Heroku connect page
* Observe/confirm the notice at the top that the schema has changed
* Scroll to the noted object
* Click "Edit"
* Next page shows "fields highlighted in red that have been removed"
* Click "Save" button at the bottom of the page

If there were an option to automate this, or to handle this scenario by default, customer would not have to continually monitor these emails and click through these fields to "un-stick" syncing.
