Track total number of WAL records, FPIs and bytes generated in the cluster.
Commit 6b466bf5f2 allowed pg_stat_statements to track the number of
WAL records, full page images and bytes that each statement generated.
Similarly this commit allows us to track the cluster-wide WAL statistics

pg_stat_wal view, and reports the total number of WAL records,
full page images and bytes generated in the , respectively.
