Wish we had some better database primitives to assemble rather than building everything on Postgres - its not ideal for a lot of things.

I see that now -- makes sense!

I'm curious to hear more about this! We agree that better primitives are required and that's why Materialize is written in Rust using using TimelyDataflow[1] and DifferentialDataflow[2] (both developed by Materialize co-founder Frank McSherry). The only relationship between Materialize and Postgres is that we are wire-compatible with Postgres and we don't share any code with Postgres nor do we have a dependence on it.

I think the [FoundationDB layer concept][1] said it well:

"When you choose a database today, you’re not choosing one piece of technology, you’re choosing three: storage technology, data model, and API/query language..."

I like the idea of [Apache Calcite][2] that provides an API to access the query planner. I think if you had more convenient access to some of the underlying components you could build a lot of cool stuff. There's too much magic where you punch in an SQL command or a config and hope it eventually does what you need.

I haven't look too much into the internals, but I'm keen to do so soon.
