exec_save_simple_expr did not account for the possibility that standard_planner would stick a Materialize node atop the plan of even a simple Result, if CURSOR_OPT_SCROLL is set. This led to an "unexpected plan node type" error. This is a very old bug, but it'd only be reached by declaring a cursor for a "SELECT simple-expression" query and explicitly marking it scrollable, which is an odd thing to do. So the lack of prior reports isn't too surprising.
