Hello
There is weired peace of code in reorderbuffer.c:
```
/* delete from list of known subxacts */
if (txn->is_known_as_subxact)
{
/* NB: nsubxacts count of parent will be too high now */
dlist_delete(&txn->node);
}
/* delete from LSN ordered list of toplevel TXNs */
else
{
dlist_delete(&txn->node);
}
```
As you see `if` an `else` branches are exactly the same. I wonder
whether this is a bug or code just requires a bit of cleaning. In the
latter case here is a patch.
According to `git log` both branches were introduced in one commit
b89e1510. I added author and committer of this code to CC since they
have much better understanding of it than I do.
