Based on the proposal of patch 0002, the code would throw an error after cleaning up the shared memory state. The generation and refcount number assigned inside pgstat_init_entry() would not matter as well because the entry created by dshash_find_or_insert() would be entirely gone. So I am not sure what's the point you are trying to make here. -- Michael
