replyI'm not in the "use Postgres for everything" camp, but only because I think it's too complex to be used like that. It should be replaced with a bunch of simple primitives in this role. No SQL and query planning magic please.

We need "frameworks" (so each sub-component can be used as-is or even swapped) and even wondering what a "system level" data engine could be.
