In WordPress, when I change the slug of one of the posts, WordPress generally is able to automatically redirect it.

We're using WordPress as a backend for a SPA, and we aren't able to use these redirects.

Is there a way to get a list of all renamed pages with their correct permalink?

At present, I'm trying to look through the posts table to then compare revision guid attributes, but WordPress obviously is already doing something similar, so I'm hoping there is a function that I can use?

Any general pointers in the right direction would be appreciated, should I be looking for revisions, posts a field in the options table...
