Show HN: PgHook – Docker image that streams PostgreSQL row changes to webhooks

I needed real-time updates in a web UI whenever PostgreSQL table rows change, so I built PgHook. It's a 23 MB Docker image (10.1 MB compressed), .NET9 AOT-compiled, that streams logical replication events and sends them to a configurable webhook.

In my setup, the webhook converts events to SignalR messages that push updates to the UI.

I know about Debezium but I needed something minimal, and I like playing with csharp.
