I haven't down-voted the post, but I'd say it's a bit misleading.
Firstly, it's not quite true "Uber migrated away because of write amplification" because they named multiple other reasons contributing to that decision. (And yes, not all of those reasons were quite valid, but that's a different discussion.)
Secondly, it's patently false that Postgres sets up local replication writing into a local file. That's plain bogus.
