Isn't the whole point to avoid the reconnection overhead, especially for connection poolers? DISCARD ALL shouldn't cause any cleanup that wouldn't otherwise occur when a session disconnects. True global data (not just session global) should be excluded.
The GD is global to the session only (Like temp tables).
A better wording of the promise would be: "discard all" leaves the session in the same state it would be in if the underlying connection were dropped and re-established.
Except that it doesn't.
