That would require introspecting arbitrary relational schemas and trying to represent them as an object graph. I don't think something like this can be done automatically and reliably.

That said, we have a tentative plan to introduce support for external databases (through FDWs, so not necessarily Postgres). The mapping specification would have to be explicit though.

Glad to hear about the FDWs ... but wouldn't foreign keys be your friend here? What else would you need, really, to layer this on an existing DB?

If your schema consistently uses synthetic primary keys, maybe like the ones produced by some active record ORMs, then, yes. Theoretically, we could make an adapter that would make EdgeDB "understand" Django schemas, for example.
