Thread: Problem with pg_upgrade
Hello, I am trying to use pg_upgrade to upgrade data from 9.1.4 to 9.2beta2. Although the upgrade completed successfully, vacuumdb --all --analyze-only gives an error. I tried upgrading two binary backups of the same production database from different days, and both returned the exact same error . The output I got for both trials is as follows: First trial: 1. postgres@sparedb1:/data/pg$ sh analyze_new_cluster.sh 2.

When it is done, your system will 5. have the default level of optimizer statistics. 6. 7.

ISTM that pg_upgrade should check that the old cluster was shut down
cleanly, ie pg_control has state = "shut down". AFAICT from some
testing, it currently only checks that there is no postmaster.pid file,
which is easily bypassed by users who might not realize that it's not
safe to run pg_upgrade against a filesystem backup.
BTW, I also noticed while trying to test this that pg_upgrade is
currently completely broken for the case of taking PGDATAOLD or
PGDATANEW from the environment rather than switches. This is because
the existing coding in option.c fails to set up the "pgconfig" fields
in such cases.

I am confused. pg_upgrade certainly starts/stops the old and new server with pg_ctl before copying any files --- isn't that sufficent? > BTW, I also noticed while trying to test this that pg_upgrade is > currently completely broken for the case of taking PGDATAOLD or > PGDATANEW from the environment rather than switches.

Fixed with the attached patch, and backpatched to 9.2. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +

The omnipitr-backup-slave process takes online backups from the standby, and this is done everyday. This process connects to the master and calls a pg_start_backup and then looks for a restore point on the standby after that WAL address. So i don't think I need to shut down the server. Also, it is the omnipitr-backup-slave process that makes a separate backup for xlog. If you run vacuumedb now, does everything later work fine? I'm not sure about that. Didn't try anything else after that. The 9.2beta2 server starts without errors though.

My guess is if you try pg_upgrade without omnipitr-backup-slave, and it works, odds are something about your use of omnipitr-backup-slave is wrong. > Also, it is the omnipitr-backup-slave process that makes a separate backup for > xlog. > > > If you run vacuumedb now, does everything later work fine? > > > I'm not sure about that.

If something was wrong with the cluster, why did vacuumdb on new server run successfully when I followed Craig's suggestion of running vacuumdb on old server first, before performing the upgrade, and then ran vacuumdb on new one?

My guess is there is something odd about the old cluster that was somehow fixed by the vacuumedb on the old clsuter that can't be fixed by vacuumdb on the new cluster. --------------------------------------------------------------------------- > > On Fri, Jul 6, 2012 at 4:05 PM, Bruce Momjian <bruce@momjian.us> wrote: > > On Fri, Jul 06, 2012 at 04:03:38PM -0400, Payal Singh wrote: > > The omnipitr-backup-slave process takes online backups from the standby, > and > > this is done everyday.
