NAME

       SPI_saveplan - save a prepared statement

SYNOPSIS

       SPIPlanPtr SPI_saveplan(SPIPlanPtr plan)

DESCRIPTION

       SPI_saveplan copies a passed statement (prepared by SPI_prepare) into memory that will not
       be freed by SPI_finish nor by the transaction manager, and returns a pointer to the copied
       statement. This gives you the ability to reuse prepared statements in the subsequent
       invocations of your procedure in the current session.

ARGUMENTS

       SPIPlanPtr plan
           the prepared statement to be saved

RETURN VALUE

       Pointer to the copied statement; or NULL if unsuccessful. On error, SPI_result is set
       thus:

       SPI_ERROR_ARGUMENT
           if plan is NULL or invalid

       SPI_ERROR_UNCONNECTED
           if called from an unconnected procedure

NOTES

       The originally passed-in statement is not freed, so you might wish to do SPI_freeplan on
       it to avoid leaking memory until SPI_finish.

       In most cases, SPI_keepplan is preferred to this function, since it accomplishes largely
       the same result without needing to physically copy the prepared statement's data
       structures.
