This is certainly true. We have never, not once, had a problem with
PostgreSQL losing production data. It is hard to break even if you
try (although I've managed a couple times in tests, with enough
ingenuity. It took more ingenuity than other things I've had to
break, mind you). But insurance is insurance, and telling managers,
clients, or regulatory bodies, "Don't worry, PostgreSQL never
breaks," is not going to fly.

One PITR-provided advantage that you cannot get with the replication
approach, by the way, is this one: "Junior DBA issued 'DELETE FROM
million_dollar_table;' at 05:00 on Saturday. I want to go back to
04:59." Your replicated database will have the same problem as the
main one.
