Even with the patch, if "test ! -f ..." is used in archive_command,
you may still *easily* get the trouble that WAL archiving keeps failing?

Instead, we should consider and document "better" command for
archive_command, or implement something like pg_archivecopy command
into the core (as far as I remember, there was the discussion about
this feature before...)?
