I have a Fedora system with Postgres version 8.3 and I want to downgrade to 8.2 because of a compatibility issue. I've been using yum for everything, but it's my first time with this package manager, and I don't know how to downgrade things.
So how do I tell it to give me a specific version of a package?
EDIT: I managed to get this working by following by downloading the specific packages as per skymt's suggestion, plus installing their GPG key. All I had to do was
rpm --import RPM-GPG-KEY-PGDG
yum localinstall postgresql-8.2.10-1PGDG.f9.i386.rpm
yum localinstall .....
And so on. However, this was fairly clunky and I'm still hoping that there's an easier way. If anyone knows of how to get YUM to target a specific version without resorting to this, please let me know so that I'll be able to do this next time.
