We upgrade multi-TB databases in just a couple minutes using
pg_upgrade using the hard-link option. That doesn't count
post-upgrade vacuum/analyze time, but depending on your usage you
might get away with analyzing a few tables before letting users in,
and doing the database-wide vacuum analyze while the database is in
use.
One of the other options might be better for you, but this one has
worked well for us.
