To save "snapshot" backups for the long term, we generate a list of
the specific WAL files needed to reach a consistent recovery point
from a given base backup.  We keep monthly snapshot backups for a
year.  We currently determine the first and last file needed, and
then create a list of all the WAL files to save.  We error out if
any are missing, so we do skip the FF file.
