Unless I’ve missed something, Postgres doesn’t have automatic index creation, nor does it have JSON introspection to automatically convert it to a normalized schema (which is insane; I love it). It also doesn’t do any kind of sharding on its own, though of course forks like Citus exist. It definitely doesn’t do RAC / Exadata (not sure which part this falls under), where multiple nodes are connected and use RDMA to treat a bunch of SSDs as local storage.

I love Postgres, and am not a huge fan of Oracle as a corporation, but I can’t deny that their RDBMS has some truly astounding capabilities.
