Hello,


I doing PITR using following doc.
http://www.mkyong.com/database/postgresql-point-in-time-recovery-incremental-backup/

But when I am doing recovery till the specific time so I change parameter
in recover.conf file.
i.e. restore_command = 'cp /opt/PostgresPlus/archive/%f %p'
recovery_target_time = '2011-12-22 07:27:08'

when I restart ppas 9.0 server then I got following error: (this is in log
file)

LOG: database system was shut down at 2011-12-22 08:21:11 IST

is it possible that the timestamp that you put there ('2011-12-22
07:27:08') is before the time that you issued the command pg_stop_backup?
you can check that by looking at the backup.label file where is says when
the backup was finished.

you can only use point in time recovery after the point when you issued the
pg_stop_backup command and the backup was finished b/c up to that point you
need to recover all the relevant wal archives to bring your database into a
consistent mode. after that point you can stop at any time since the db is
already consistent.

It looks like you don't have a good copy of the
00000001000000000000000F WAL file. If you can retrieve a good copy
from somewhere, you should be able to proceed. If not, you should
go to an earlier base backup -- that will let you restore a
consistent version of the database for as far as you have good WAL
files.

You should also review your procedure for copying WAL files. We had
occasional problems like this when we were using samba shares; we've
had none since we copied the files to a directory on the database
server and used rsync to copy them off.
