Oh, of course, it's directly the fault of the patch that added support for partitioned target tables. I concluded that a verbatim backpatch wasn't too suitable because a04daa97a had changed a lot of the APIs here. So I left the APIs for the xxx_internal() functions alone. Otherwise the patch pretty much works as-is in v13. regards, tom lane
