To migrate the data to the new database, run pg_upgradecluster. This is
a wrapper around pg_upgrade which knows about details of a standard
Debian/Ubuntu PostgreSQL installation (like directory layout, etc.), so
it should be simpler and safer than invoking pg_upgrade yourself (and
pg_upgrade is hidden in /usr/lib/postgresql/*/bin to prevent you from
invoking it accidentally).
