The data checksums launcher and workers were exposed in pg_stat_io with the same broad set of object/context combinations as general background workers. However, several of those entries can never accumulate I/O statistics for these processes, such as bulkwrite, relation init, temporary relation, and launcher vacuum entries. Teach pgstat_tracks_io_object() and pgstat_tracks_io_op() about the actual I/O performed by the data checksum processes. Keep the entries needed for catalog scans, including bulkread catalog scans, worker relation processing with a vacuum access strategy, and WAL writes and initialization, while excluding WAL reads and other object/context combinations that can never be used.
