Fixed regressions

Fixed regression in :meth:HDFStore.select where the where clause on a datetime index silently returned empty results when the index had non-nanosecond resolution (:issue:64310)

.. --------------------------------------------------------------------------- .. _whatsnew_302.bug_fixes:

Bug fixes ^^^^^^^^^

:func:col and expressions derived from it failed with power (**) and matrix multiplication (@) operators (:issue:64267)
Assigning :attr:pd.NA to a string column could trigger a PyArrow error and corrupt data (:issue:64320)
Bug when using :func:col with Python functions :func:bool, :func:iter, :func:copy, and :func:deepcopy either failed or produced incorrect results; these now all raise a TypeError (:issue:64267)
Fixed bug in the :meth:~Series.sum method with python-backed string dtype returning incorrect value for an empty Series and ignoring the min_count argument (:issue:64683)
Fixed bug where :meth:DataFrame.div ignored the axis argument when used with level for MultiIndex columns (:issue:64428)
