Description

Note that compute functions will still get generated, they'll just error when used:

>>> pc.month_interval_between(pa.array([1, 2], pa.timestamp('s')), pa.array([3, 4], pa.timestamp('s')))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/lidavidm/Code/upstream/arrow-13548/python/pyarrow/compute.py", line 181, in wrapper
    return func.call(args, None, memory_pool)
  File "pyarrow/_compute.pyx", line 341, in pyarrow._compute.Function.call
    return wrap_datum(result)

    return pyarrow_wrap_array(MakeArray(datum.array()))

    klass = get_array_class_from_type(sp_array.get().type())
  File "pyarrow/array.pxi", line 2420, in pyarrow.lib.get_array_class_from_type
    return _array_classes[data_type.id()]
KeyError: 21
