SPIPlanPtr SPI_prepare_cursor(const char * command, int nargs, Oid * argtypes, int cursorOptions)
SPI_prepare_cursor is identical
SPI_prepare, except that it also
allows specification of the planner's "cursor
options" parameter. This is a bit mask having the values
shown in nodes/parsenodes.h for the
options field of DeclareCursorStmt.
SPI_prepare always takes the cursor options as
number of input parameters ($1, $2, etc.)
pointer to an array containing the OIDs of the data types of the parameters
integer bit mask of cursor options; zero produces default behavior
Useful bits to set in cursorOptions include CURSOR_OPT_SCROLL, CURSOR_OPT_NO_SCROLL, CURSOR_OPT_FAST_PLAN, CURSOR_OPT_GENERIC_PLAN, and CURSOR_OPT_CUSTOM_PLAN. Note in particular that CURSOR_OPT_HOLD is ignored.
