according to the TupleDesc's natts, not the number of physical columns in the tuple. The previous coding would do the wrong thing in cases where natts is different from the tuple's column count: either incorrectly report error when it should just treat the column as null, or actually crash due to indexing off the end of the TupleDesc's attribute array. (The second case is probably not possible in modern PG versions, due to more careful handling of inheritance cases than we once had. But it's still a clear lack of robustness here.) The incorrect error indication is ignored by all callers within the core PG distribution, so this bug has no symptoms visible within the core code, but it might well be an issue for add-on packages. So patch all the way back.
