Robert Haas 26bd08fb5c doc: Note that plan advice does not affect cached plans ...

Plan advice is consulted only at plan time.  When a cached plan is
re-executed, no re-planning occurs, so updated advice has no effect.
DISCARD PLANS can be used to discard cached plans, but only affects
the sessions in which it is executed.
