I've got myself into a bit of trouble trying to upgrade the version of postgres on a server and now I want to revert back as it's caused some issues. I'm trying to back track and to uninstall a couple of repo's. I added the repo's with:zypper addrepo -t YUM http://packages.2ndquadrant.com/postgresql-z-suse/zypper/sles-11sp3-s390x pgzypper addrepo -t YUM http://packages.2ndquadrant.com/postgresql-z-suse/zypper/sles-11sp3 pgsrcIs there any way I can run a command to uninstall these? I usually work with Debian and I'm in uncharted territory. I've googled this and someone suggested locating the repo directory and manually deleting them but others disagreed. 
One liner to remove repo added with zypper addrepo on OpenSuse?
opensuse;repository;zypper
