I have been ramming my head against the wall for the past two
evenings, trying to get PITR working and it's gotten to the point
where I need to ask someone for help.
I'm basically trying to follow the instructions in the manual in
chapter 23.3.
Here's how I'm starting out:
===================
Contents of 'data':
PG_VERSION
base
global
pg_clog
pg_hba.conf
pg_ident.conf
pg_multixact
pg_subtrans
pg_tblspc
pg_twophase
pg_xlog
postgresql.conf
postmaster.opts
data/pg_xlog/archive_status is empty.
I have the following line in postgresql.conf:
archive_command = 'cp -i %p /mnt/server/archive/wal/%f < /dev/null'
/mnt/server/archive/wal is empty.
Here's my procedure:
===============
1. pg_ctl start -l logfile
2. SELECT pg_start_backup('label');
3. tar -zcf /mnt/server/archive/file/backup.tar.gz . (the contents of
'data')
4. SELECT pg_stop_backup();
5. pg_ctl stop
6. I now delete the contents of 'data' (making a copy before hand)
7. In 'data': tar xzvf /mnt/server/archive/file/backup.tar.gz
8. echo \"restore_command = 'cp /mnt/server/archive/wal/%f %p'\" >
recovery.conf
9. pg_ctl start -l logfile
And here are the logs:
================

Where oh where might I be going wrong? I'd be grateful for any
suggestions.
