Run Postgres yourself. If Postgres developers are going to compromise their own software, it isn’t going to be to mislabel your shipping containers.

If someone were really interested in changing the number on your shipping container, blockchain can’t prevent someone with a $1 can of spray paint from changing it.

Sure, but the point here is to not lose the records too, which someone could trivially change if they own the Postgres DB. When I have a shared record of a container and somebody repaints its SN, at least I know I lost it, and I can also easily claim that I did not forge the records too because they signed the record with their wallet.
