Cloud SQL for PostgreSQL: Faster CMEK Re-encryption
Cloud SQL for PostgreSQL now supports zero-downtime re-encryption for instances and replicas using customer-managed encryption keys (CMEKs). This enhancement significantly speeds up the re-encryption process by performing in-place disk re-encryption without creating backups. The change benefits users managing their encryption keys for PostgreSQL instances, offering a more efficient and seamless update experience.

- Cloud SQL for PostgreSQL
Cloud SQL for PostgreSQL now supports significantly faster re-encryption of instances and replicas protected by customer-managed encryption keys (CMEKs), and re-encryption now completes with zero downtime. The steps to re-encrypt your instances and replicas are unchanged, but the operation now re-encrypts the underlying disks in-place, without creating re-encryption backups. For more information, see Re-encrypt an existing CMEK-enabled instance or replica .
