True. Note as well that 9.4 has introduced recovery_min_apply_delay to somewhat leverage such errors by delaying replication (well actually it delays the moment when WAL records doing transaction commit are applied at recovery, and does so after a consistent point has been reached at recovery). Still this does not replace the fact that a robust backup strategy should combine both physical and logical backups.
