NAME
       SPI_cursor_move - move a cursor

SYNOPSIS
       void SPI_cursor_move(Portal portal, bool forward, long count)

DESCRIPTION
       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.
