Isn't that already in section 12.2.1 of the documentation?

     Using pg_control to get the checkpoint position speeds up the
     recovery process, but to handle possible corruption of pg_control,
     we should actually implement the reading of existing log segments
     in reverse order -- newest to oldest -- in order to find the last
     checkpoint. This has not been implemented, yet.
