Amen.  We do this for anything not supplied with RHEL, although our
first trip is usually a quick look at the EPEL repos to see if they have
a suitable build we can use.

As an aside, though, I personally gave up the gotta-have-the-latest
treadmill some time ago.  There's a lot to be said for letting a
distribution engineering team spend the time and effort tracking
security fixes and suchlike.

(And to answer the original question, I'd use RHEL or CentOS; but these
things tend to devolve into a simple way of exposing the distro
prejudices of the responders)

As many other people have this idea, you can just re-use their
back-porting work: backports.org
Never had a quality issue with these packages and updates are quickly
available. YMMV.

I'd consider Debian to be a perfectly reasonable choice...  

In order to conclude that something else is specifically superior,
you'd need to define some metrics that allow evaluating along the
lines that:

   "A is better than B in areas X and Y.
B is better than A in area Z.

Because factor Z is really important to us, that means we prefer
distribution B."

Absent of evaluation criteria, you'll just see people saying "Oh, I
like {SomeThing} about my favorite distribution, and maybe you'd like
that too."

FWIW: I've just noticed that Debian experimental carries pg 9.0beta1, it was 
uploaded 3.5., so thats not bad, taking into account that it was released 
only a few days earlier.

http://packages.debian.org/experimental/postgresql-9.0

Experiemntal packages can be installed directly into Debian unstable (sid) 
installations and can often be recompiled rather trivially into Debian 
testing.  Depending on how old Debian stable is, compiling there may take a 
bit more work (especially for building the stuff depending on the not so 
slowly moving targets like python, ruby etc.) but is certainly doable.

Not that I'd recommend using beta packages from experimental on a production 
system.

My experience (mostly with FreeBSD, but it scales to other systems as
well) is that if you have some stuff managed by your package manager
and some from hand-built sources, that ultimately you end up in a
world of hurt.  It has to be all or none one way or the other, or your
package manager will try to install things you already have, possibly
breaking how you set things up, or you end up with missing bits and
pieces.

We choose to make packages locally to satisfy all of our dependencies
as it also greatly simplifies management across 30+ servers.

And were the versions the same? If you're going to go to the
trouble of hand-compiling, I'm willing to bet that you went to
the trouble of finding more recent versions of the software.

That is not how you test things.

Not to mention that compiler optimizations increase the chance of

Without breaking down how much of that speed increase was from Apache,

Some thoughts:

If the machine is only used as a database server, consider Red Hat 
Enterprise Linux/CentOS. They are great for installing and keeping 
up-to-date - just add the PGDG repo into the yum repos configuration 
files. It matters not if I'm on 5.1, 5.2, 5.3... The updates to the RPMs 
tend to become available concurrently with source releases and the 
file/directory/path settings tend to follow PostgreSQL's worldview. But 
if the machine is used for multiple purposes you may be frustrated by 
the long-term stable nature of RH. For example, if you plan on using PHP 
on the same machine you will need to stick with the RH default version 
which is a couple releases old or go through the hassle of 
configuring/compiling PHP or locating third-party RPMs - PHP does not 
supply RPMs.


Ubuntu, with its 6-month release cycle, tends to include more recent 
versions of software. But there is a delay getting updates and it is 
more of a headache installing new PostgreSQL on older Ubuntu. There 
isn't a nice, neat source for PGDG vetted .debs. You will also get an 
installation tailored for the Debian/Ubuntu view of where files should 
go. On the other hand, this structure lends itself nicely to running 
different major versions in parallel and they provide some scripts to 
handle major-version upgrades. The scripts have worked for me but YMMV. 
At least the old installation is still available if the upgrade fails.


Cheers,
Steve

I have fond memories of having a single script to do all that on
RedHat 5.1 back when I started out.  (Not RHEL 5.1, RedHat 5.1)
Honestly, for our single purpose corporate intranet machine it was
perfection, and that machine ran 24/7 for years after I left with only
minor maintenance.  We were on RedHat 9 or something when I left.  I
still build mutliple builds of pgsql, now on RHEL 5.latest, and it's
pretty easy.  I just make a configure.local file, use that for each
new version etc so it's just like the last.

But for php I use eaccelerator and it's a necessity even with powerful
servers.  Drops load on heavy web servers by factors of 10 or 20.

@Devrim, I may be wrong at sometimes, because I have not done any
qualification research on this. All I have learned from Google and
self experience.
I run my site (see my signature) on a self managed VPS. I was using
the default PGSQL RPM from the fedora repository, the site was getting
way slow. So I compiled all the stuff apache, php and postgresql with
custom gcc flags, which improved performance like hell.
This may not apply to all, its my experience; not an illusion because
I asked other site contributors also about the speed, they said it was
much better.

Note that we can always use more people to help Debian, too.  If you feel 
Debian is too slow uploading new pg versions [1]: perhaps you can change 
this by helping Martin preparing and testing new packages.  Packaging stuff 
for Debian is not magic, it's just Makefiles, Perl/shell scripts and stuff 
like this.  (And I, too, like the parallel installation of different pg 
versions and was very much missing it when I was forced to work on SuSE for 
some business stuff...)

... and you can always mix testing and unstable.  If your testing 
installation is not too old, usually not much fiddling with dependencies is 
involved.  Reading the apt_preferences manual page and some other Debian 
documentation to understand how packages are moved between 
experimental/unstable/testing is strongly recommended, though.

I'd hesitate to use unstable for a production machine, though.  Even testing 
is not always a good idea, since security support for testing is not quite 
as good as for stable.

Yes, Debian QA can take a couple of weeks for things to reach you after 
release.  From some perspectives that's considered a good thing.  If the 
update is to fix a security bug, it's possible that's a problem 
instead.  In that rare case, you can always learn to build your own 
packages.


Ultimately, if your true priority is "access to new versions of Postgres 
as soon as possible", you can do that on any Linux distribution by 
building from source and potentially packaging the result up as if it 
were a standard packages.  That should be way, way down on the list of 
things that factor into what version of Linux you deploy though.  If 
you've got support from your administration team using Debian, I think 
you'd be crazy to switch to another OS just to speed up getting newer 
versions of PostgreSQL.  Put a little time into learning how to build 
your own packages instead, to work around this one perceived flaw, and 
you'll be way ahead of the mess that comes with switching distributions 
altogether.

I am not talking about removing the data I am talking of not beeing
able to access it because the database itself is still in the old
version.

Unless you use the migrate script, which just started to appear, you
had to dump the data, to the rpm upgrade and import the data.

I really prefer the debian way where I can run them parallel and
therefore test everything before I do a switchover.

Re: [GENERAL] What Linux edition we should chose?

[Clemens Schwaighofer]

Hi,

I run debian/testing since years and it is the best in my opinion.
Besides the fact that new versions come in quite fast (after the wait
phase from unstable to testing) the upgrade for major versions (eg 8.3
to 8.4) is very simple as it does not override the old files but does
a parallel install.

This is something I do miss from the RPM versions. Because if you do
not dump the data before you upgrade, you are quit screwed.

@Devrim: You got the reason from @Alan.
Self compilation has the advantage of custom gcc flags like -O3 -march
-msse, etc. which can improve performance.
Building RPMs is not a task that everyone can do. It requires
extensive reading about rpmbuild and writing the specfile.
So if you install directly from source without RPM, it won't satisfy
the libpq.so dependency, so you cannot install applications using yum.
This is not the case with Arch PKGBUILD, because the PKGBUILD is just
a bash script.

Depends. If you build a compat- RPM to supply the original system-provided 
client libpq.so it will usually satisfy their package requirements. If you 
don't, then you might find yourself needing to rebuild other packages to 
coexist with upgraded PostgreSQL versions. Neither option is terribly 
difficult to accommodate.

It is not "many" weeks actually -- it is just their QA policy.

Anyway, I've been running an RPM repository, which has up2date packages,
which are releases on the same date as PostgreSQL updates are releases.
You may want to consider it, if you are familiar with CentOS,RHEL or
Fedora:

Now we
can change our OS and it is question what Linux edition will be the

as  possible, for Debian sometimes we had to wait many weeks for
official packages.

Right, but some sysadmins don't want to see development libraries on the

And with ArchLinux its even more easy to keep track of its updates.
You don't have to make weird configurations. Just use a PKGBUILD
script from ABS (Arch Build System), change some settings, run makepkg
and your package is created with the default clean configuration. No
/usr/local stuff.

we have choose Mandriva, it is quite easy to install and to maintain,  and  
speaking about packages there are many support in them, including PGSQL

You should use whatever you are comfortable with.
I would go with ArchLinux for its ease of use and making packages. RPM
and DPKG are much harder to build than ArchLinux's .pkg.tar.xz
Also, if you install some libraries like python clients or some
software depending on PgSql from the repositories in RPM/DPKG based
OS, you will have a tough time with the dependency stuff.
ArchLinux provides a PKGBUILD already from ABS (Arch Build System)
which contains all the dependency satisfiers. It serves two purposes-
depedency satisfaction and self compilation.

If it makes you feel better, build your own RPMs (or
$package-style-of-choice).  This is actually a pretty good idea if you
are on a package-manager-based platform, as it makes it far simpler to
keep track of exactly what you've got installed.  It's generally not
hard to take the source package supplied by your distro and stick a
new minor-release source tarball into it.

Usually that's pretty easy: for upgrading the minor version (e.g. from 8.3.1
to 8.3.3) it should be enough to compile the new sources, stop server, run
`make install` and run the server with new binaries. Upgrading from 8.3 to
8.4 can be easily done using dump from current version. There is nothing
wrong to run the new and old postgres versions parallel so you can copy data
from one database to another.
There is also pgmigrator, but I haven't checked that yet.

Remember to make a database dump before the whole operation :)

Yeah it is. But what is it going to be an upgrade process? On a
production box?
Any experience to share on upgrading from source on Debian?

Use whatever you want. I've been compiling PostgreSQL on Ubuntu, Debian and
Gentoo so far without any problems.
Choose the distribution that you're familiar with, take PostgreSQL sources
and compile as you wish.

That's not true, and it's no problem to build PG from source.
