I find it pretty unlikely that Slony would be unable to help you
upgrade here. Obviously you can upgrade one database at a time.
Also, mostly it's not the database size what's a concern, but rather
the size of the largest table.
As I recall (I could be wrong) Slony syncs the whole set as a single
transaction. So if he has his entire database as a set he may
have a problem regardless of the largest or smallest table. I would

agree that 30 million rows is likely not a problem but he should still
check his velocity.
FWIW, Londiste doesn't work with sets and, instead, maintains
replication state, as well as giving you the option to add/remove
tables from replication, on a table-by-table which can be observed
from the command line.
