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.
