### Describe the bug, including details regarding any error messages,
version, and platform.
RecordBatchReader.cast() was added in pyarrow 16..
Error: pyarrow.lib.ArrowTypeError: Field 0 cannot be cast from date32[day]
to date32[day]
```
>>> import pyarrow as pa
>>> import datetime
>>>
>>> t = pa.Table.from_pylist([{"abc": datetime.date.today()}])
>>> tb = t.to_reader()
>>> tb.cast(t.schema)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "pyarrow\\ipc.pxi", line 800, in pyarrow.lib.RecordBatchReader.cast
File "pyarrow\\error.pxi", line 154, in
pyarrow.lib.pyarrow_internal_check_status
File "pyarrow\\error.pxi", line 91, in pyarrow.lib.check_status
pyarrow.lib.ArrowTypeError: Field 0 cannot be cast from date32[day] to
date32[day]
```
In my use case:
I'm trying to cast the results of a database query from:
Field 0 is a string, Field 1 is a date32[day], Field 2 is a **double**
to
Field 0 is a string, Field 1 is a date32[day], Field 2 is a **float**
But I'm getting Field 1 cast error on dates..
