Well I think that it is controlled by the packager. In a released Fedora
version, you are only going to get bug fix updates, which don't have that
issue. You do need to be careful doing upgrades because the base postgres
version can change between Fedora versions. (You also need to be extra careful
if you care about postgres while running rawhide.) After you have upgraded
postgres it is too late to use the old data (though people are working on
improvements on that front). So you need to be sure to do the dump before the
upgrade.
