I am sorry for being unclear. directories are
/backup1/data
/backup1/archive
and
/backup2/data
/backup2/archive

backup1 has data and archive directories copied after 1st shutdown
backup2 has data and archive directories copied after 2nd shutdown

Now i created recovery.conf in backup1/data and i replaced pgstats.stat
from backup2 in backup1 (in data/global)
Now i start Server pointing to backup1, where it uses recovery.conf to
rollback to database snapshot after first shutdown

I expected a failure because pgstats.stat do not reflect statistics of
snapshot created from backup1 directory (1st shutdown) but of backup2 (2nd
shutdown)
