SPI_keepplan — save a prepared statement
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 C function in
the current session.
the prepared statement to be saved
0 on success;
NULL or invalid
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.
