I think EXPLAIN VERBOSE would add that bit of detail.
Indeed it does! I literally just now experimented with this and was returning to the ML reply to myself to avoid wasting more of anyone's time.
Would a tiny patch to the PREPARE docs be accepted? I'd like to help clarify investigating `plan_cache_mode` for future readers.
Thanks for replying, regards,
