That's still true. standby_mode=off is the same as what you have in PG
8.4. You can still use pg_standby etc. with that.

True. You could work around that by using a script instead of plain
'cp', or by making sure that no partial files appear in the archive in
the other end.
Or we could check for the partial WAL file case in the server. But
Windows copy command is worse than that, and sets the file size before
finishing copying.
From a user point-of-view, it might be simplest to provide a
"restore_directory" option, besides restore_command, and handle the copy
ourselves.
