Hm, that's not appropriate to prove that the re-use never happens. I also checked the PostgreSQL documentation of its serial type for which is probably used by Django for the AutoField. It seems to me that the serial sequence generator is not well suited for re-using deleted elements, but I'm not sure. It would be great if a Django or general database expert could calrify this.
