NAME

       SPI_finish - disconnect a procedure from the SPI manager

SYNOPSIS

       int SPI_finish(void)

DESCRIPTION

       SPI_finish 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
       elog(ERROR). In that case SPI will clean itself up automatically.

       If SPI_finish is called without having a valid connection, it will return
       SPI_ERROR_UNCONNECTED. There is no fundamental problem with this; it means that the SPI
       manager has nothing to do.

RETURN VALUE

       SPI_OK_FINISH
           if properly disconnected

       SPI_ERROR_UNCONNECTED
           if called from an unconnected procedure
