Yeah, exactly.  Thus, pushed.

Yup.  However I notice that there are a few other callers of
expression_planner() that do not involve the optimizer for anything
else.  Maybe it makes sense to have a separate header file that's just

#include "nodes/primnodes.h"
extern Expr *expression_planner(Expr *expr);
extern bool plan_cluster_use_sort(Oid tableOid, Oid indexOid);

Seems it could be used by a large percentage of files currently
including planner.h.
