The fly postgres create command deploys an ordinary Fly app running Postgres on a volume. Fly's documentation is explicit that this is not a managed database service: failover behavior is whatever the bundled tooling provides, backups are volume snapshots rather than point-in-time recovery unless you add something yourself, and version upgrades and disk resizing are your responsibility.
A single-node cluster inherits the single-volume, single-host failure mode of Fly volumes, so it is one host problem away from downtime.
Plan for it the way you would plan for self-hosted Postgres on a VM: take logical dumps to object storage on a schedule, monitor disk usage because a full volume stops writes, and rehearse a restore before you need one. Fly has since introduced a separate managed Postgres offering, so confirm which one an app actually uses before assuming a database has managed backups behind it.
