Well, other than postfix's virtual mapping rules, that's what I mean: postfix has no idea if he's supposed to be MX host or not, because it's treating the virtual mapping rules as "authoritative", as far as I know.

Since we have no means to know that the MX records were modified, then we can't "remove" those virtual mapping rules from our database.

Is there something I'm missing?

"virtual" maps. So at this point, if we send this customer an email at
his domain, the email will be delivered "internally" instead of being
sent to his NEW external MX host.

So how can we configure postfix so that it will "realize" that the
mail should be routed to the NEW MX host?

In the same way that you configure Postfix so that it will
realize that it becomes MX host for a new customer's domain.
