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
counters.
New columns wal_records, wal_fpi and wal_bytes are added into the
pg_stat_wal view, and reports the total number of WAL records,
full page images and bytes generated in the , respectively.

This is missing a catversion bump, due to the changes in view
names. Noticed that because I got errors like
-- There must be only one record
select count(*) = 1 as ok from pg_stat_wal;
- ok
-----
- t
-(1 row)
-
+ERROR: function return row and query-specified return row do not match

when running tests against a pre-existing cluster after rebasing a
development tree.
Thanks for reporting this! You are right.
Sorry I forgot to bump that. I will do that.
