Hi,
Good day all.
I’ve upgraded PG from 9.3.4 to 9.3.13 using apt-get install postgresql-9.3. I’m wondering as a blackout plan, how to downgrade it back to 9.3.4?
Thanks,
Suya

Hi,
You can follow below steps:
1. Stop the cluster .
2. If you have backup of old bin and postgresql.conf revert it and start
.
3. Or uninstall and reinstall old binaries again.

Thanks JD for the response. My question is more specific on how to reinstall old binary using apt-get install.
Thanks,

You can sometimes do "apt-get install postgresql-9.3=9.3.4-1"
But often the OS cannot work out where to get hold of the requested version.
Alternatively you can check in /var/cache/apt/archives.
If the .deb file for the downlevel version is still there (copy it out so
it's not cleaned up in future), and you can do "dpkg -i postgres-9.3_9.3.4-1
.deb"
Failing that, you can download the downlevel deb file from somewhere.
(perhaps here? https://launchpad.net/ubuntu/+source/postgresql-9.3 )

On Debian we have snapshots (http://snapshot.debian.org/), not sure if
Ubuntu provides a similar service, but the Postgres packages are similar
enough that you could try that as a last resort.

Thank you Markus, good to know that Debian has the snapshot service which is very handy. I’m not a Ubuntu fan, I prefer CentOS over Ubuntu…
Thanks,
Suya

Hi David,
This is the most complete solution I’ve got so far.
With apt-get install, OS says it cannot find the version, as you said.
sh@preview-db-1:~$ sudo apt-get -s install postgresql-9.3=9.3.4-1
[sudo] password for sh:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Version '9.3.4-1' for 'postgresql-9.3' was not found
Looked at the archives directory, there’s no postgresql packages, probably get cleaned up…
The last option does work! I found the deb file in launchpad http://launchpadlibrarian.net/170211692/postgresql-9.3_9.3.4-1_amd64.deb and will download it as a backout plan for the upgrade.
Thanks a lot for the very useful suggestion!
Thanks,
Suya
