Urrk. Didn't think of that. I always install from source on Unix, which
doesn't have the problem. And the Windows port doesn't have this problem
- it will put the binaries in a version dependant directory.

One could claim the packages are broken ;-), but that's not gonig to
help here, I know...

(I always install in pgsql-<version>, and then symlink pgsql there..)

You assume they know enough to download it. If they don't know to look
for it, they still won't find it.

But the bottom line: I can see how it would be helpful if you're on a
distro which packages postgresql in a way that prevents you from
installing more than one version at the same time.
