#  Testing scenarios when columns depend on generated columns, i.e. such as    #
#   - a generated column is based on a generated column                            #
#   - a "real" column on which a generated one is renamed/dropped              #
#   - a generated column involved in partitioning is renamed/dropped           #
#                                                                              #
