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.
