I'm more in favour of in-place upgrade. This might seem risky, but I
think we can expect users to backup their PGDATA directory before they
start the upgrade.
I don't trust pg_dump because
. it doesn't help when the old postmaster binaries are not longer
available
. it does not always produce scripts that can be loaded without manual
intervention. Sometimes you create a dump and cannot restore it with
the same Postmaster version. RTA.
