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.
