I'm not sure what you mean, but it does apply to same-server PITR
recovery too. In that case, again, if you copy the partial segment to
pg_xlog when doing the PITR recovery, clearly you already somehow have
access to the partial segment, and if you want to do another PITR to the
same point, you should just copy it again.
