> This is a followup of [#31964|https://github.com/apache/spark/pull/31964]
> We should only quote the column name when nested column predicate pushdown is
> enabled, otherwise the data source side may not have the logic to parse the
> quoted column name and fail. This is not a problem before
> [#31964|https://github.com/apache/spark/pull/31964] , as we don't quote the
> column name if there is no dot in the name. But
> [#31964|https://github.com/apache/spark/pull/31964] changed it.
