I think you are making a bunch of assumptions that you haven't written down, so it is hard for me to guess what your assumptions are. In the boring, normal, standard setup that people have been using Postgres for in the last 20 years, data does not get lost so long as you have a main server and a sufficient number of backups running in sync, possibly at some distance. A question like "How not to lose data when your main server is destroyed by a fire" is an old question that database engineers have been working on for 40 years, and for which there are many good answers. But I think you're imagining some kind of automatic link between the distributed nature of the blockchain leading to a distributed Postgres. But you would need to write out what your assumptions actually are before I could respond to them.
