Thanks! I think it's a bug.
There are two clients: "the client that executed
pg_log_backend_memory_contexts()" and "the client that issued the query
that was the target of the memory context logging", but I was only
concerned about the former when I wrote that part of the code.
The latter is not expected.
It seems better to use LOG_SERVER_ONLY as the attached patch.
The patch was successfully applied and there was no regression test
error on my environment.
