hi,
    I found the code in 'backend/access/transam/xloginsert.c' as that:
XLogRecordAssemble:
  if (prev_regbuf && RelFileNodeEquals(regbuf->rnode, prev_regbuf->rnode))
         {
             samerel = true;
             bkpb.fork_flags |= BKPBLOCK_SAME_REL;
             prev_regbuf = regbuf;
         }
         else
             samerel = false;

There is the only place that prev_regbuf is assigned, so prev_regbuf will never 
be assigned.
The patch will fix it, Thanks.


Thanks, good catch! Committed.
