SPI_KEEPPLAN(3) 			    PostgreSQL 9.2.7 Documentation			      SPI_KEEPPLAN(3)

NAME
       SPI_keepplan - save a prepared statement

SYNOPSIS
       int SPI_keepplan(SPIPlanPtr plan)

DESCRIPTION
       SPI_keepplan saves a passed statement (prepared by SPI_prepare) so that it will not be freed by SPI_finish nor
       by the transaction manager. 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
       0 on success; SPI_ERROR_ARGUMENT if plan is NULL or invalid

NOTES
       The passed-in statement is relocated to permanent storage by means of pointer adjustment (no data copying is
       required). If you later wish to delete it, use SPI_freeplan on it.
