We have no simple point to stop replay.
Well, except for "immediately" - just one easy stop. But I agree that this is not the best option. Simple and clear, but not best one for data when we want to replay as much as possible from archive.

But in case of still working primary (with archive_command) we choose quite random time to promote. A random time when the primary did not save the new wal segment.
or even when a temporary error of restore_command occurs? We mention just cp command in docs. I know users uses cp (e.g. from NFS) without further error handling.
