def total_count(column_name = :all, options = {}) #:nodoc:
  # #count overrides the #select which could include generated columns referenced in #order, so skip #order here, where it's irrelevant to the result anyway

    c = except(:offset, :limit, :order)

    # Remove includes only if they are irrelevant
