Urgent PostgreSQL security updates for Debian/Ubuntu

PostgreSQL just released security updates. 9.1 (as found in Debian testing and unstable and Ubuntu 11.10 and later) is affected by a critical remote vulnerability which potentially allows anyone who can access the TCP port (without credentials) to corrupt local files. If your PostgreSQL database exposes the TCP port to any potentially untrusted location, please shut down your servers and update now!

PostgreSQL 8.4 for Debian stable (squeeze) and Ubuntu 8.04 LTS and 10.04 LTS also got an update, but these are much less urgent.

Debian and Ubuntu advisories for all stable releases, as well as Debian testing are going out as we speak. The updates are already on security.debian.org and security.ubuntu.com.

I also uploaded updates for Debian unstable (8.4, 9.1, and 9.2 in experimental) and the Ubuntu backports PPA, but it will take a bit for these to build as we don’t have embargoed staging builds for those. Christoph updated the apt.postgresql.org repository as well.

Warning: If you use the current Ubuntu raring Beta-2 candidate images, you will still have the old version. So if you do anything serious with those installations, please make sure to upgrade immediately.

Update: Debian and Ubuntu security announcements have been sent out, and all packages in the backports PPA are built.

Please see the official FAQ if you want to know some more details about the nature of the vulnerabilities.

PostgreSQL 9.2 final available for Debian and Ubuntu

PostgreSQL 9.2 has just been released, after a series of betas and a release candidate. See for yourself what’s new, and try it out!

Packages are available in Debian experimental as well as my PostgreSQL backports PPA for Ubuntu 10.04 to 12.10, as usual.

Please note that 9.2 will not land any more in the feature frozen Debian Wheezy and Ubuntu Quantal (12.10) releases, as none of the server-side extensions are packaged for 9.2 yet.

PostgreSQL 9.2 RC1 available for testing

The unstoppable PostgreSQL team just announced the first release candidate of 9.2, with several bug fixes since the Beta 4. If you haven’t tested 9.2 yet, now is the time! Remember that you can run a copy of your 8.4 or 9.2 cluster in parallel for testing with pg_upgradecluster.

If you use Debian, 9.2rc1 will be available in experimental in a few hours. For Ubuntu, you can get packages for all supported releases from my PostgreSQL backports PPA as usual.

Enjoy!

New PostgreSQL microreleases with two security fixes

New PostgreSQL microreleases with two security fixes and several bug fixes was just announced publically.

I spent the morning with the packaging orgy for Debian unstable and experimental (now uploaded), Debian Wheezy (update sent to security team), Ubuntu hardy, lucid, natty, oneiric, precise (LP #1008317) and my backports PPA.

I tested these fairly thoroughly, but please let me know if you encounter any problem with these.

Debian/Ubuntu Packages for PostgreSQL 9.2 Beta 1

The first Beta of the upcoming PostgreSQL 9.2 was released yesterday (see announcement). Your humble maintainer has now created packages for you to test. Please give them a whirl, and report any problems/regressions that you may see to the PostgreSQL developers, so that we can have a rock solid 9.2 release.

Remember, with the postgresql-common infrastructure you can use pg_upgradecluster to create a 9.2 cluster from your existing 8.4/9.1 cluster and run them both in parallel without endangering your data.

For Debian the package is currently waiting in the NEW queue, I expect them to go into experimental in a day or two. For Ubuntu 12.04 LTS you can get packages from my usual PostgreSQL backports PPA. Note that you need at least postgresql-common version 0.130, which is available in Debian unstable and the PPA now.

I (or rather, the postgresql-common test suite) found one regression: Upgrades do not keep the current value of sequences, but reset them to their default value. I reported this upstream and will provide updated packages as soon as this is fixed.

PostgreSQL 9.1 final packages available for Debian/Ubuntu

Hot on the heels of the PostgreSQL 9.1.0 release I am happy to announce that the final version is now packaged for Debian unstable, the current Ubuntu development version “Oneiric”, and also in my Ubuntu backports PPA for Ubuntu 10.04 LTS, 10.10, and 11.04.

Enjoy trying out all the cool new features like builtin synchronous replication or per-column collation settings for correctly handling international strings, or an even finer-grained access control for large environments. Please see the detailled explanation of the new features.

As already announced a few days ago, 9.0 is gone from Ubuntu 11.10, as it is still only a development version and not an LTS. 9.1 will be the version which the next 12.04 LTS will support, so this slightly reduces the number of major upgrades Ubuntu users will need to do. However, 9.0 will still be available in Debian unstable and backports, and the Ubuntu backports PPA for a couple of months to give DB administrators some time to migrate.

Dropping PostgreSQL 9.0 packages for Debian/Ubuntu/backports

PostgreSQL 9.1 has had its first release candidate out for some two weeks without major problem reports, so it’s time to promote this more heavily. If you use PostgreSQL, now is the time to try it out and report problems.

We always strive to minimize the number of major versions which we have to support. They not only mean more maintenance for developers, but also more upgrade cycles for the users.

9.0 has not been in any stable Debian or Ubuntu release, and 9.1 final will be released soon. So we recently updated the current Ubuntu development release for 11.10 (“oneiric”) to 9.1. In Debian, the migration from 8.4/9.0 to 9.1 is making good progress, and there is not much which is left until postgresql-9.0 can be removed.

Consequently, I also removed 9.0 from my PostgreSQL backports PPA, as there is nothing any more to backport it from. However, that mostly means that people will now set up installations with 9.1 instead of 9.0, and won’t magically make your already installed 9.0 packages go away. They will just be marked as obsolete in the postgresql-common debconf note.

If you want to build future 9.0 packages yourself, you can do this based on the current branch: bzr branch lp:~pitti/postgresql/debian-9.0, get a the new upstream tarball, name it accordingly, add a new changelog with a new upstream version number, and run bzr bd to build the package (you need to install the bzr-builddeb package for this).

Update 2011-09-09: As I got a ton of pleas to continue the 9.0 backports for a couple of months, and to keep it in Debian unstable for a while longer, I put them back now. I also updated the removal request in Debian to point out that I’m mainly interested in getting 9.0 out of testing. I don’t mind much maintaining it for a couple of more months in unstable. My dear, I had no idea that my backports PPA was that popular!

Debian/Ubuntu packages for PostgreSQL 9.1 Beta 2

Hot on the heels of the Announcement of the second 9.1 Beta release there are now packages for it in Debian experimental and backports for Ubuntu 10.04 LTS, 10.10. and 11.04 in my PostgreSQL backports for stable Ubuntu releases PPA.

Warning for upgrades from Beta 1: The on-disk database format changed since Beta-1. So if you already have the beta-1 packages installed, you need to pg_dumpall your 9.1 clusters (if you still need them), and pg_dropcluster all 9.1 clusters before the upgrade. I added a check to the pre-install script to make the postgresql-9.1 package fail early to upgrade if you still have existing 9.1 clusters to avoid data loss.

Packages for PostgreSQL 9.1 Beta 1 now available

Two weeks ago, PostgreSQL announced the first beta version of the new major 9.1 version, with a lot of anticipated new features like synchronous replication or better support for multilingual databases. Please see the release announcement for details.

Due to my recent moving and the Ubuntu Developer Summit it took me a bit to package them for Debian and Ubuntu, but here they are at last. I uploaded postgresql-9.1 to Debian experimental; currently they are sitting in the NEW queue, but I’m sure our restless Debian archive admins will get to it in a few days. I also provided builds for Ubuntu 10.04 LTS, 10.10. and 11.04 in my PostgreSQL backports for stable Ubuntu releases PPA.

I provided full postgresql-common integration, i. e. you can use all the usual tools like pg_createcluster, pg_upgradecluster etc. to install 9.1 side by side with your 8.4/9.0 instances, attempt an upgrade of your existing instances to 9.1 without endangering the running clusters, etc. Fortunately this time there were no deprecated configuration options, so pg_upgradecluster does not actually have to touch your postgresql.conf for the 9.0 →9.1 upgrade.

They pass upstream’s and postgresql-common’s integration test suite, so should be reasonably working. But please let me know about everything that doesn’t, so that we can get them in perfect shape in time for the final release.

I anticipate that 9.1 will be the default (and only supported) version in the next Debian release (wheezy), and will most likely be the one shipped in the next Ubuntu LTS (in 12.04). It might be that the next Ubuntu release 11.10 will still ship with 9.0, but that pretty much depends on how many extensions get ported to 9.1 by feature freeze.

PostgreSQL 9.0 final released

After 20 days of final polishing and maturing since the release candidate, the PostgreSQL team released the final 9.0 version today.

Hot off the press, I uploaded postgresql-9.0 final into Debian unstable; they will not go into Debian Squeeze, because Squeeze is frozen and it will take a long time to port all the packaged server side extensions to 9.0.

If you are on Ubuntu 10.04 LTS or Ubuntu 10.10, you can add my PostgreSQL backports for stable Ubuntu releases PPA, which will carry 9.0 until it can be moved to the official Ubuntu backports (i. e. when 9.0 goes into Ubuntu Natty).

Enjoy, and kudos to the PostgreSQL team!
