serialize_pandas round trip fails on integer columns

    Details

      Description

      This roundtrip fails, since the Integer column isn't converted to a string after deserializing

      In [1]: import pandas as pd
      im
      In [2]: import pyarrow as pa
      
      In [3]: pa.deserialize_pandas(pa.serialize_pandas(pd.DataFrame({"0": [1, 2]}))).columns
      Out[3]: Index(['0'], dtype='object')
      

      That should be an {{ Int64Index([0]) }} for the columns.
