Anything can be a message queue if you use it wrongly enough
This isn't theoretical; many companies do PostgreSQL async 1:N physical replication, by using e.g. https://pgbackrest.org/ to have the primary push WAL segment files (a.k.a. "the last n milliseconds of packets" in the write-ahead log) as objects to S3, and then to have all read-replicas fetch from S3 and replay.
> You could do even better if you out-of-band signal the readiness so you do not need to poll while idle.
S3 and its clones have "object lifecycle notifications", where you can be informed by a push-based mechanism whenever a new object is put into the bucket.
But — what do you have to do, to get these notifications?
Subscribe to a message queue that S3 puts them into.

Kubernetes postgres backups
I haven't explored the territory in awhile but for bare-metal, you can't go wrong with Percona Distribution, which includes pgBackRest and a minimal web-ui. No one ever got fired for using Percona, etc.

Cloud SQL is not great
Backups are limited. These days, pgbackrest is the go-to backup solution for PostgreSQL, and having used it I am very impressed so far. It provides full backups, differential, and incremental, as well as archiving of WAL segments for point in time recovery. It allows great flexibility in schedules and destinations for backups, how long to keep backups for, how many full backups. For example, you can have backups made to a local disk, and other backups to an external S3-compatible bucket, each with their own settings and schedules (e.g., scheduled via cron).
