PostgreSQL provider adds point-in-time recovery

The CloudNative PostgreSQL provider now supports point-in-time recovery (PITR), letting you restore a PostgreSQL cluster to a specific moment using archival backup data.

Specify the target recovery point via spec.dataSource when creating or restoring an instance. Previously, restores were limited to full backup snapshots, so recovering from an accidental change meant losing everything written after the last snapshot.

Point-in-time recovery is available now for all PostgreSQL clusters using the CloudNative PG provider.
