Show HN: Honker – Postgres NOTIFY/LISTEN Semantics for SQLite

Honker is a new SQLite extension that adds Postgres-style NOTIFY/LISTEN semantics, enabling durable pub/sub and task queues without needing Redis or a separate broker. It uses SQLite's WAL file for cross-process event notifications with millisecond latency and ships with language bindings for Python, Node, Ruby, Go, Elixir, and C++. The approach consolidates queues and business data in a single SQLite file, eliminating dual-write problems and operational overhead.
