Обсуждение: Using pg_migrator to upgrade 8.3->8.4
We are looking to upgrade out 8.3 db to 8.4. The full dump and restore is not very attractive due to the downtime involved. pg_migrator is an attractive option, but we have butted up again the integer datetime timestamp problem: "Old and new pg_controldata date/time storage types do not match. You will need to rebuild the new server with configure --disable-integer-datetimes or get server binaries built with those options." We also noticed that the are non id rpms available for 8.3, but we couldn't find any for 8.4 here: https://projects.commandprompt.com/public/pgcore So, is the best option to compile postgres from source? Is there anyway to change the storage of timestamps in our 8.3 db online (I am guessing no...)? Mostly I just need a sanity check before I waste a bunch of time :)

All good info... With respect to RPMs, I was actually referring to postgres84 rpms with non-integer datetime prebuilt.

Oh, I don't think anyone has made any of those, but I can see it would be useful. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + If your life is a hard drive, Christ can be your backup. +

Excuse by noobness, but where can I find the source RPMs for Centos? I searched for a while without luck. And which svn repository are you referring to? I assume not the postgres CVS repo.

So are the RPMs for postgres with non-integer datetimes available? :) For centos? :) On Feb 2, 2010, at 2:00 PM, Bruce Momjian wrote: > Devrim GÜNDÜZ wrote: > -- Start of PGP signed section. >> On Mon, 2010-02-01 at 11:12 -0500, Bruce Momjian wrote: >>> >>> >>> No idea if anyone is building RPMs for it >> >> Of course I'm building ;) >> >> We have pg_migrator 8.4.14 for RHEL/CentOS 4,5 and Fedora 12-i386. > > Oh, wow, that's nice. > > -- > Bruce Momjian <bruce@momjian.us> http://momjian.us > EnterpriseDB http://enterprisedb.com > > + If your life is a hard drive, Christ can be your backup. +

Yep, O will go down that road if I am not duplicating any work. In my experience building RPMS from SRPMS rarely just "works":) -Mark On Feb 2, 2010, at 3:36 PM, Bruce Momjian wrote: > Mark Corner wrote: >> >> So are the RPMs for postgres with non-integer datetimes available? :) For centos? :) > > No, but you were told how to modify the RPM configuration file to build > it that way, I think. > > --------------------------------------------------------------------------- > > >> >> On Feb 2, 2010, at 2:00 PM, Bruce Momjian wrote: >> >>> Devrim G?ND?Z wrote: >>> -- Start of PGP signed section. >>>> On Mon, 2010-02-01 at 11:12 -0500, Bruce Momjian wrote: >>>>> >>>>> >>>>> No idea if anyone is building RPMs for it >>>> >>>> Of course I'm building ;) >>>> >>>> We have pg_migrator 8.4.14 for RHEL/CentOS 4,5 and Fedora 12-i386. >>> >>> Oh, wow, that's nice. >>> >>> -- >>> Bruce Momjian <bruce@momjian.us> http://momjian.us >>> EnterpriseDB http://enterprisedb.com >>> >>> + If your life is a hard drive, Christ can be your backup. + > > -- > Bruce Momjian <bruce@momjian.us> http://momjian.us > EnterpriseDB http://enterprisedb.com > > + If your life is a hard drive, Christ can be your backup. +

Really? It's supposed to. At least at Red Hat, the RPMs *are* built
from the SRPMs, nothing behind the curtain. In recent releases they're
even built in a minimally-loaded chroot to ensure that there are not any
missing BuildRequires: (which did use to be a hazard).
