An Arrow Flight, Postgres wire protocol, Arrow over HTTP & Quack protocol server for DuckDB as an extension
A mock PostgreSQL server that speaks just enough of the wire protocol to connect with psql. Built for learning and hacking.
Fine-grained access control for Postgres (row filters, column masking, blocking) via a SQL-aware proxy. Free and source-available. Warehouses on the roadmap.
Transparent PostgreSQL wire-protocol query cache and read acceleration proxy with automated table invalidation under 35MB RAM
