According to #Description following entries are missing in the pg_hba.conf (added by spacewalk-setup): host rhnschema rhnuser 127.0.0.1/8 md5 host rhnschema rhnuser ::1/128 md5 local rhnschema postgres ident map=usermap local postgres postgres ident map=usermap In addition to that I'm not aware upgrade documentation would recommend to use the --skip-db-install option: Command: ./install.pl --upgrade --skip-db-install (in combination with the --upgrade option) I'm closing this BZ as I assume the customer didn't follow the upgrade documentation for his Satellite 5 upgrade.
