[HACKERS] warning in twophase.c

Been seeing this warning recently:

twophase.c: In function ‘RecoverPreparedTransactions’:
twophase.c:1916:9: warning: variable ‘overwriteOK’ set but not used
[-Wunused-but-set-variable]  bool  overwriteOK = false;        ^~~~~~~~~~~

As the message says, the value of overwriteOK is not used anywhere in
RecoverPreparedTransactions:
        bool        overwriteOK = false;
       /*        * It's possible that SubTransSetParent has been set before, if        * the prepared transaction
generatedxid assignment records. Test        * here must match one used in AssignTransactionId().        */       if
(InHotStandby&& (hdr->nsubxacts >= PGPROC_MAX_CACHED_SUBXIDS ||                            XLogLogicalInfoActive()))
      overwriteOK = true;
 

Couldn't we get rid of it?

Thanks,
Amit
