Depends. A lot of postgres usage is often "things that might as well be redis", like session tokens (but the library we imported came configured for postgres) so if the postgres goes down, as long as it can be restarted it won't be the end of the world even if all the data were wiped. Probably there is also an 80/20 for most users where it's not awful if you can restore from a cold storage, say 12h, backup.
