SPI_cursor_move — move a cursor
Synopsis
void SPI_cursor_move(Portal portal, bool forward, long count)

SPI_cursor_move skips over some number of rows in a cursor. This is equivalent to a subset of the SQL command MOVE (see SPI_scroll_cursor_move for more functionality).
Arguments
Portal portal : portal containing the cursor
bool forward : true for move forward, false for move backward
long count : maximum number of rows to move
Notes
Moving backward may fail if the cursor's plan was not created with the CURSOR_OPT_SCROLL option.
