I have been working on showing all WAL stats in the pg_stat_io [1]
view but currently it is blocked because the size of the WAL read IO
may vary and it is not possible to show this on the pg_stat_io view.
Proposed a fix [2] for that (by counting IOs as bytes instead of
blocks in the pg_stat_io) which you already reviewed :).
