PITR is a recovery technique, allows you to restore the database to an
arbitrary point in time, not neccessarily the latest (so, for instance,
you can recover to just before your overzealous assistant adminstrator
made a total mess of your accounting system).
to utilize PITR, you need A) a base backup, and B) *all* the WAL
archives since that base backup was taken up to the point at which you
wish to recover.
