 can be achieved with <CODE
CLASS="FUNCTION"
>SPI_prepare</CODE
> followed by
   <CODE
CLASS="FUNCTION"
>SPI_execute_plan</CODE
>; however, when using this function
   the query plan is always customized to the specific parameter values
   provided.
   For one-time query execution, this function should be preferred.
   If the same command is to be executed with many different parameters,
   either method might be faster, depending on the cost of re-planning
   versus the benefit of custom plans.
