I recently upgraded PostgreSQL, and now this happens:
# /etc/init.d/postgresql start
An old version of the database format was found. You need to upgrade the data format before using PostgreSQL. See /usr/share/doc/postgresql-8.3.8/README.rpm-dist for more information.
apparently your upgrade procedure was far from perfect.
Unfortunately, I upgraded due to a hardware failure, and can't dump/undump, since I don't have the old PostgreSQL server anymore.
Can I upgrade the data format w/o installing Postgres 7.2 (my "data/base/1/PG_VERSION" file says "7.2")?
no.
If not, can Fedora 11's "yum" install Postgres 7.2 (so I can at least do a clean install/uninstall and then re-install 8.3.8)?
Don't know, but I'd rather try this:
compile 7.2 from source, bring up a temporary postgres 7.2 instance, dump it (using pg_dumpall from 8.3), and load the dump into 8.3.
