Re: Upgrade from 9.1 to 9.10

Please bare with my knowledge, but is there any way to find if the past
installations were done using YUM?

This is all standard redhat installation/administration stuff...

# rpm -qf /usr/pgsql-9.2/bin/postgres
postgresql92-server-9.2.5-1PGDG.rhel6.x86_64

(replace 9.2 with 9.1)... if its installed from the PGDG RPM like that, then it came from the postgres yum repository.

also verify they actually installed that repository, and didn't just manually jam the RPMs on there...

# rpm -qf /etc/yum.repos.d/pgdg-9*
pgdg-centos90-9.0-5.noarch
pgdg-centos92-9.2-6.noarch

you should see the 91 version.
