As far as I recall, nobody there was that specific about the form of
it. PostgreSQL arguably has non-integrated multi-master replication
now, and I've seen log-based implementations which operated through
daily dial-up connectivity as far back as 1984. (Statewide in Alaska,
and city-wide in New York City, neither of which could afford to keep
full-time communications up for all the relevant sites.)
I did point out the options mentioned here for PostgreSQL:
