Hi all, i'm trying to setup PITR on my postgresql ( i run version 1.8.11 );
Following the docs and tips from the list this is what i made:

1) set up a crontab which copys the last-created WAL file in
/home/postgres/WAL
2) set up a shell-script as a the archive_command: it copyes WAL files
from pg_xlog dir in /home/postgres/WAL
3) set up a shell script for doing the backup. It connects to DB and
then issues "SELECT pg_start_backup('full-bck');" , then it execute "tar
--exclude data/pg_xlog -cvzpf archive.tar.gz data" , and finally "SELECT
pg_stop_backup();".

For testing purposes i use another server in which i installed the same
version of PostgreSQL. In it i deleted the DATA dir (
/var/lib/pgsql/data ); then i unpacked the archive.tar.gz ; i created
the pg_xlog dir and, in it, also the archive_status one.
I setup the recovery.conf whit the recovery_command='cp
/home/postgres/WAL/%f "%p"' . I copied all the WAL files fron the
old-server to the new one in /home/postgres/WAL/.

When i try to start the DB it hangsup saying ( in the logs ):
......
LOG: database system was interrupted at 2008-04-11 09:03:48 CEST
LOG: starting archive recovery
LOG: restore_command = "cp /home/postgres/WAL/%f %p"

LOG: invalid secondary checkpoint record
PANIC: could not locate a valid checkpoint record
LOG: startup process (PID 22672) was terminated by signal 6
LOG: aborting startup due to startup process failure

......

Someone can help in understanding where is the problems ???

Thanks in advance,
