The archiver doesn't know any more about where the end-of-data is than
the archive_command does. Moreover, the archiver doesn't know whether
the archive_command cares. I think the separate module is a fine
solution.
It should also be pointed out that the whole thing becomes uninteresting
if we get real-time log shipping implemented. So I see absolutely no
point in spending time integrating pg_clearxlogtail now.
