Hindsight: I was skeptical that they'd left all the metadata (configuration/application domain data) in PostgreSQL while moving the (100x larger) business data to Vertica. At this point I'd repeat the pattern just for the sheer delight of dealing with a complex application schema in PostgreSQL. The flexibility demanded of Vertica was decidedly less in that shop.
