PITR Multiple recoveries
Hi all,
I'm trying to make my server doing PITR backup, i follow the rules on
https://www.postgresql.org/docs/9.5/static/continuous-archiving.html.
On my local server, i would like to resync multiple times my local database:
What i'm doing :
1. Stop Postgres
2. Restore Local basebackup (untar, un gzip)
3. Create recovery.conf
4. Start Postgres
5. Wait recovery.done
6. At this point, it's OK.
7. Stop Postgres
8. ..... some time passed
9. resync wals with latest
10. recreate recovery.conf
11. Start Postgres
11. Wait recovery.done
12. At this point, it's NOK. Latest wals have not been played on local
server.
Do you know what i'm missing ? Thanks
Regards,
Sebastien Boutte

Once recovery is done and the database is open, it is now a primary. It is
no longer eligible for further WAL replay.
(Unless it is was only open in standby mode.)

Hi Jeff,
You mean that ? Is this correct ?
hot_stanby = on to be sure it plays WAL and stays in standby mode ?
1. Stop Postgres
2. Restore Local basebackup (untar, un gzip)
3. Create (recovery.conf) standby_mode + hot_standby on (postgresql.conf)
4. Start Postgres
5. Wait to see in log "database system is ready to accept read only
connections"
6. To Check
7. Stop Postgres
8. ..... some time passed
9. resync wals with latest
10. recreate recovery.conf without standby_mode + hot_standby off
11. Start Postgres
11. Wait recovery.done
12. To Check
Thanks
Sebastien
