I think that this is a good idea. It does not actually overlap the proposal in [1] as the stats persistency is not the same. What this thread has taught me is that you could just plug in the stats of the new backend-level structure a PgStat_WalStats and retrieve them with a new function that returns a single tuple with the WAL stats attributes. That should be rather straight-forward to achieve. [1]: https://commitfest.postgresql.org/51/4950/ -- Michael
