I doubt it. Our archive_command works like this:
1) scp the file over to the backup server as root. It's stored in a
file named <name_of_wal>.NEW
2) When the scp finishes, ssh to the standby server and chown it to postgres.
3) Then, ssh to the standby server and rename the <name_of_wal>.NEW
file to the real WAL filename.
Only after step (3) does our standby script even see the file.
So unless there's a possibility that the master server invokes our archive
script before the WAL has finished being written, I can't see how this
could happen.
