Review follow-up (cozystack#3300):
- docs/operations/backup-classes.md: add an operator-facing upgrade note for the
two platform-wide changes this migration carries — the CloudNativePG operator
bump to 1.28.1 (with the CRD-skew fix and the Helm-CRD-upgrade caveat) and the
LINSTOR scheduler admission-webhook removal, which makes data-locality
scheduling advisory cluster-wide (spec.schedulerName no longer auto-assigned;
opt in via explicit schedulerName). These affect more than Postgres backups and
were previously only noted in a chart values.yaml comment.
- hack/e2e-chainsaw/postgres/postgres.yaml: drop stale restic-era backup fields
(s3Region, s3Bucket, cleanupStrategy, resticPassword) that no longer exist in
the Postgres backup schema; use current fields (destinationPath, endpointURL,
retentionPolicy, 6-field schedule).
