CThe table is encrypted with AWS KMS

    Encryption and indexes do not prevent PITR restore; primary key is mandatory but unrelated to PITR errors.

  3. Final Answer:

    PITR was not enabled on the source table -> Option B

  4. Quick Check:

    Restore error cause = PITR not enabled [OK]
Quick Trick: Check PITR enabled status before restoring [OK]
Common Mistakes:
MISTAKES
