I hope this is a simple question. I checked the PG wiki but didn't find an answer: http://wiki.postgresql.org/wiki/RPM_Installation I have my 8.2.3 RPMs installed. I would like to upgrade to 8.2.9. Because this is a minor version upgrade (within 8.2) I understand that I should be able to upgrade the rpm *without* dump/restore step. Now, is it correct that i don't have to stop my server and I can just execute these commands: rpm -Uvh --test postgresql-libs-8.2.9-1PGDG.rhel4.i386.rpm rpm -Uvh --test postgresql-8.2.9-1PGDG.rhel4.i386.rpm rpm -Uvh --test postgresql-contrib-8.2.9-1PGDG.rhel4.i386.rpm rpm -Uvh --test postgresql-devel-8.2.9-1PGDG.rhel4.i386.rpm rpm -Uvh --test postgresql-server-8.2.9-1PGDG.rhel4.i386.rpm And all will be okay? (I would run these without the "--test") Right now, these tests give errors. My question: I do not have to change my CONF files and data and the upgrade should work with the above? The Wiki does not address this in the upgrade section. Thanks.
