I think it's best to close the entry. There's substantial further wins possible, in particular not acquiring ProcArrayLock in GetSnapshotData() when the cache is valid improves performance substantially. But it's non-trivial enough that it's probably best dealth with in a separate patch / CF entry. Closed. Greetings, Andres Freund
