>Description</H2
><P
>   <CODE
CLASS="FUNCTION"
>SPI_finish</CODE
> closes an existing connection to
   the SPI manager.  You must call this function after completing the
   SPI operations needed during your procedure's current invocation.
   You do not need to worry about making this happen, however, if you
   abort the transaction via <TT
CLASS="LITERAL"
>elog(ERROR)</TT
>.  In that
   case SPI will clean itself up automatically.
  </P
><P
>   If <CODE
CLASS="FUNCTION"
>SPI_finish</CODE
> is called without having a valid
   connection, it will return <TT
CLASS="SYMBOL"
>SPI_ERROR_UNCONNECTED</TT
>.
   There is no fundamental problem with this; it means that the SPI
   manager has nothing to do.
