Обсуждение: postgreSQL not working after upgrade to Ubuntu 10.4
Yesterday I upgraded from Ubuntu 9.10 to 10.4. Unfortunately this has caused me serious problems with everything related to postgreSQL. It seems as though the new version of ubuntu is requiring me to use PostgreSQL 8.4 instead of 8.3 which I was previously using. I tried installing 8.4 but I can't seem to get the database to start. Has anyone had a similar problems? -- View this message in context: http://old.nabble.com/postgreSQL-not-working-after-upgrade-to-Ubuntu-10.4-tp28488130p28488130.html Sent from the PostgreSQL - general mailing list archive at Nabble.com.

You have to take care of things like that yourself. In particular, for PostgreSQL, you would need to dump all your databases using 8.3, then upgrade, then create a new 8.4 installation and restore the databases into it. Sadly PostgreSQL does not do in-place major version upgrades. In your case, you need to stop and make a couple good filesystem-level backups of your database. Then you need to find a way to either get 8.3 working on that machine, or move the database to another machine where you can get it working, so you can do the PostgreSQL backup. Then you can think about getting 8.4 setup on your upgraded machine and restore that backup into it. You should probably also read through the 8.4 release notes to see if you will require changes in any applications using those databases. -- "No animals were harmed in the recording of this episode.

Try looking at the output of: ls /etc/postgresql ls /etc/init.d/postgresql* ls /var/lib/postgresql If you did a basic upgrade you may find that both versions are installed and you just have to start the old one (then do your dumps so you can upgrade). Alternately, you may want to use the /usr/bin/pg_upgradecluster script that is typically available on Ubuntu and (usually, in reasonably vanilla cases) does the upgrade for you. In all cases, do your best to get a backup, first. Cheers, Steve

I ran into this with Fedora when they went from 8.3 to 8.4 in the middle of the life of Fedora 12 - luckily I had been doing daily pg_dumps so all I had to do was initdb under 8.4 and psql < my backup. -- Stephen Clark NetWolves Sr. Software Engineer III Phone: 813-579-3200 Fax: 813-882-0209 Email: steve.clark@netwolves.com www.netwolves.com
Thanks for all the help - I needed to an initdb and then I also had to do: sudo dpkg -i /var/cache/pat/archives/postgresql-client-8.4_8.4.3-1_i386.deb but it's finally working!! Now I just have to get all my data back but after this headache I think that will be comparatively easy! Thanks for all the help!

Yes but the install procedure should be smart enough to look and see if you are using a previous version of Postgres and prompt you if you want to continue installing the new database. > > In particular, for PostgreSQL, you would need to dump all your databases > using 8.3, then upgrade, then create a new 8.4 installation and restore the > databases into it.

Btw: it is possible to mix packages from multiple versions - you might be able to install the 8.3 again by adding "jaunty" back to /etc/apt/sources.list (not replace lucid but just add jaunty), run "apt-get update", then find the package "postgresql" in the aptitude tool, and press 'v': you then get all the versions available. Select the 8.3 version, press '+' and 'g'. I just verified this on a test fresh 10.4 installation and after 'g' I get no conflicts at all, however, 9.10 (karmic) does not have postgres 8.4, but 9.04 (jaunty) does. regards, Yeb Havinga
