Re: [CentOS-devel] Upgrading postgresql (Re: CentOS/RHEL 5.3)

Even though a PostgreSQL core developer, Tom Lane, works for Red Hat and packages the RHEL PostgreSQL packages. Upgrading PostgreSQL is a HARD thing to do without using the documented 'dump-upgrade-initdb-restore' sequence (unless you want to get multiversion installs working, and use Slony to do the migration...good luck with the multiversion! Although Debian has that piece worked out, Debian can do things during install/upgrade in .deb packages that RPM's cannot do). >However, at the least a %pre script should create an SQL dump before >upgrading major releases, so user is not left with an unusable blob. >Better would be for postgresql to ship a standalone SQL dumper, which can >read old file formats. I maintained the 'PGDG' or community upstream RPM's for PostgreSQL for five years, from 1999 to 2004. Personal reasons caused me to hand that over to Devrim, the current RPM maintainer lead. So I've fought with this issue a long time (as John knows). A %pre scriptlet has no way of reliably detecting whether it is running under Anaconda during a media-fed upgrade or from a fully installed system. If the %pre scriptlet is running under Anaconda, it cannot do an SQL dump, which requires a major portion of the normal system to be present and running to complete. This is not the case in an Anaconda-mediated upgrade, during which many basic system services are simply not there. Then there is the disk space issue (making sure you don't run out). Oh, and compiled C functions. There was once a pg_upgrade program that could do some of this stuff; however, it can break in subtle ways. The PostgreSQL system catalogs that are part of the database contain things that are part of the core system, including functions, operators, and the like. And sometimes the actual tuple format changes from one release to another... Now, it has been a while since I last looked at the upgrading situation; if you want to learn more about it, read the archives of the pgsql-hackers list and search for the various and many upgrade discussions. As a user, I have a CentOS 4 system that at this point in time cannot be upgraded past its current PostgreSQL version due to the need to store photographs from Microsoft Access as large objects. The support for the method used is not in any subsequent version, and in fact doesn't work on anything but the version shipped with CentOS 4. We will have to recode the application to get it ported, unfortunately. Any automatic upgrade of this system would break, and break badly. The moral is that, as a server administrator, you must be ever diligent to make sure that 'upgraded' software doesn't dramatically break things; and you cannot rely on the OS upgrade to do it. (I'm thinking BIND, Apache modules, java versions, amavisd and sendmail, among other things that tend to break in upgrades....) -- Lamar Owen Chief Information Officer Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 828-862-5554 www.pari.edu

Google's SoC 2009
by Karanbir Singh 22 Jan '09

22 Jan '09

hi, Is there anyone who would like to take ownership of a CentOS effort into GSoC ? Its something we have often thought about ( I have anyway ), but time restrictions have meant that nothing has happened on this front in many years. Here is what I am expecting : - Someone who can research and work out whats involved, document it somewhere ( wiki perhaps ? ) - Lead the CentOS pitch to google, hopefully pushing through to us getting accepted into the scheme. If that happens then : - Organise wish lists, prioritise what projects we are looking at - Organise the 'student' pool - Organise the 'mentor' pool - Be *the* GSoC-CentOS person. No idea how much time this is going to take, but it should be safe to assume its going to be a few hours/week commitment. And its going to be over a significant portion of the year. Anyone ? * I dont mind if more than 1 person wants to take this on as a team. -- Karanbir Singh : http://www.karan.org/ : 2522219@icq

Help offer on Sparc front

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have just received a SunBlade150 which I would like to put to good use. I understand there is a Centos port underway for the Sparc line. If it is possible to trash the harddisk and fill it with the bare stuff to make it work I am willing to lend access to the system for developers and also do some things myself. I am not a programmer but I can spot the incidental error and maybe fix a typo or at least do my best to provide serious feedback in attempts to capture, reproduce and solve issues. If there is a basic kit somewhere to turn the former Solaris machine and set it on the road to Centos 5 I am willing to add my weight and push the cart along.

presto / deltarpm
by Karanbir Singh 05 Jan '09

05 Jan '09

hi, The idea of yum-presto and deltarpm support on mirror.centos.org is something that seems to be worth visiting again. I am just wondering if there is anyone who would like to grab the issue, do the testing, workout whats involved and then try and come up with an implementation plan ? Would be good if you already knew how yum and repomd type repositories worked. Anyone interested and have the time ? -- Karanbir Singh : http://www.karan.org/ : 2522219@icq
