Hi Hackers,

The current code comment says that the replication stream on a slot with
the given targetLSN can't continue after a restart but even without a
restart the stream cannot continue. The slot is invalidated and the
walsender process is terminated by the checkpoint process. Attaching a
small patch to fix the comment.
