RecoveryTargetTLI dead variable in XLogCtlData

Hi all,

I just bumped into $subject, a variable that is never set and never used:
--- a/src/backend/access/transam/xlog.c
+++ b/src/backend/access/transam/xlog.c
@@ -631,8 +631,6 @@ typedef struct XLogCtlData
    TimeLineID  replayEndTLI;
    /* timestamp of last COMMIT/ABORT record replayed (or being replayed) */
    TimestampTz recoveryLastXTime;
-   /* current effective recovery target timeline */
-   TimeLineID  RecoveryTargetTLI;

Thanks,
