Operating system:   Fedora Core 3
Description:        RPM: wrong quoting of error message about old database
format after upgrading
Details:

[bertheau@dicaprio ~]$ sudo /etc/init.d/postgresql start

An old version of the database format was found.\nYou need to upgrade the
data format before using PostgreSQL.\nSee (Your System's documentation
directory)/postgresql-8.0/README.rpm-dist for more information.

This is the literal output. The \n's are overquoted.
