+The previous default behavior (checksums disabled) can be obtained using the
+new option --no-data-checksums. Note that pg_upgrade will reject upgrading
+between clusters with different checksum settings, so if the old cluster was
+initialized without checksums (the previous default), then the new cluster
+will need to be initialized with --no-data-checksums in order to allow
+pg_upgrade to succeed.
