SPI_scroll_cursor_move — move a cursor

void SPI_scroll_cursor_move(Portal portal, FetchDirection direction,
                            long count)

SPI_scroll_cursor_move skips over some number of rows in a cursor. This is equivalent to the SQL command MOVE.

`Portal +`_`+portal`_: portal containing the cursor
`FetchDirection +`_`+direction`_: one of FETCH_FORWARD, FETCH_BACKWARD, FETCH_ABSOLUTE or FETCH_RELATIVE
`long +`_`+count`_: number of rows to move for FETCH_FORWARD or FETCH_BACKWARD; absolute row number to move to for FETCH_ABSOLUTE; or relative row number to move to for FETCH_RELATIVE

SPI_processed is set as in SPI_execute if successful. SPI_tuptable is set to NULL, since no rows are returned by this function.

See the SQL FETCH command for details of the interpretation of the `direction and count` parameters.

Direction values other than FETCH_FORWARD may fail if the cursor’s plan was not created with the CURSOR_OPT_SCROLL option.
