Note that AFAIK we currently don't dump any such hash-tables, so if there's a bug there it only affects the case of the user *re*dumping with a special config, which AFAIK we do not intend to officially support yet for 27.1. > I wasn't talking about the hash tables; that bug needs to be fixed, > indeed. Not sure which bug you're referring to, because the one discussed recently (linked to the pdumper's need to rehash tables) should be fixed already (Pip Cet provided both that simple fix I installed as well as a subsequent better but more intrusive fix).
