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.

I think there should be a big, fat warning in the release notes.
Something like:

WARNING: Upgrading to version X.Y requires a full dump/restore cycle.
Please download the appropriate dump-utility from http://postgresql.org/dumputils/X.Y/
and make a copy of your database before installing the new version X.Y.


And then link to a dir with the statically linked pg_dump (and -all) for
the most common platforms. I must admit, I did not know that one should
use the new tool in a cyclus (and I have used Pg almost exclusively
since 7.0). That could also be the place to add a line about version S.T
is now considered obsolete and unsupported.
