The project in which we are working requires assigning a personalized taxonomy to users who in turn are related to a custom post type, that is, we want to tag posts and users with the same custom term.
The problem is that the user object generates ids independently of the posts, that is, there is a risk that a user has the same id as a post with which the relationship of the taxonomies would not help.
The question: is there a possibility, either by sql or via wp callback, that users and posts have a single id altogether? That is, do not overlap.
Thank you in advance for your attention.
