A session-end hook seems pretty problematic to me: you simply cannot
guarantee that it will run at all. (Consider process crash or server
abort cases.) So anything built on the assumption that it gets to run
at session end is going to be inherently unreliable.
Or even "reset session" as is often used by connection poolers depending on what semantics are trying to be captured.
