apply_handle_tuple_routing(), having detected and reported that the tuple it needed to update didn't exist, tried to update that tuple anyway, leading to a null-pointer dereference. logicalrep_partition_open() failed to ensure that the LogicalRepPartMapEntry it built for a partition was fully independent of that for the partition root, leading to trouble if the root entry was later freed or rebuilt. Meanwhile, on the publisher's side, pgoutput_change() sometimes attempted to apply execute_attr_map_tuple() to a NULL tuple. The first of these was reported by Sergey Bernikov in bug #17055; I found the other two while developing some test cases for this sadly under-tested code. Diagnosis and patch for the first issue by Amit Langote; patches for the others by me; new test cases by me. Back-patch to v13 where this logic came in.
