If you wish to recover into some child timeline (that is, you want to return to some state that was itself generated after a recovery attempt), you need to specify the target timeline ID in recovery_target_timeline <https://www.postgresql.org/docs/13/runtime-config-wal.html#GUC-RECOVERY-TARGET-TIMELINE>. You cannot recover into timelines that branched off earlier than the base backup." [1][2]
