Show HN: Letter – Relationship-based access control (ReBAC) Postgres extension

Hi HN,

This extension provides relationship-based access control (ReBAC) for PostgreSQL.

It's a rewrite of the DDLX permissions system I wrote while working at ElectricSQL, but just for internal use in Postgres rather than for a distributed sync system.

It lets you model the kind of permissions you need for complex multi-tenant applications directly inside the DB.

This extension is still just a beta and not production ready, it needs bunch more testing so don't use it with anything important yet.

I'd run some benchmarks to see how well it scales with the number of users and rules.
