FWIW, if you're looking at PostgreSQL-at-humungo scale, there are a few options around. TimescaleDB, Citus (which Azure now offers as a service called Hyperscale DB) and there are others I always feel terrible for overlooking. I work for VMware and get along well with folks who work on Greenplum. It's still doing massive workloads with massive amounts of data for lots of customers, has the ability to operate over blob stores with predicate pushdowns and recently merged up to parity with the PostgreSQL 12 upstream[0]. It's the fruit of a six year effort to return to the upstream from a heavily modified fork of 8.3. A truly monumental effort.
