 dump. Release backups must therefore be paired with the persistent storage
 volume backup policy. Use `--inventory-mode sha256` for final release
 evidence.

+An old persistent volume can also retain glibc collation metadata for the
+empty `postgres` and `template1` system databases. If `createdb` fails for that
+reason, first complete and verify the production backup, then reindex each
+affected system database and run `ALTER DATABASE <name> REFRESH COLLATION
+VERSION`. Never refresh before reindexing, and never treat this maintenance as
+a substitute for the isolated restore proof.
