int SPI_execute_plan_with_paramlist(SPIPlanPtr plan,
                                    ParamListInfo params,
                                    bool read_only,
                                    long count)   SPI_execute_plan_with_paramlist executes a plan
   prepared by SPI_prepare.
   This function is equivalent to SPI_execute_plan
   except that information about the parameter values to be passed to the
   query is presented differently.  The ParamListInfo
   representation can be convenient for passing down values that are
   already available in that format.  It also supports use of dynamic
   parameter sets via hook functions specified in ParamListInfo.
  
      execution plan (returned by SPI_prepare)
