This commit only affects comments, so I'm confident it doesn't break code, though I did not run the tests.
I understand that the pg_xlog directory was renamed to pg_wal (confirmed that this is in the changelog too), so the comment changes seem correct.
I am marking this Ready for Committer.
The new status of this patch is: Ready for Committer
