      Description

      Defect Tracker #24522: Temp table cardinality is currently only used for staging tables. It would also be generally useful for ad hoc queries to have the TempTableStoreImpl maintain the cardinality of the tables. Other costing information could actually be incorrect now (such as column min/max) depending upon what has been selected into a temp table.
