## Summary by CodeRabbit

* **Documentation**
* Added a troubleshooting guide for a broadcast-message warning observed
in Postgres logs.
* Explains why messages may be dropped when partitions/replication
streaming aren’t yet available and when they become available.
* Provides diagnostic steps and remediation (ensure a subscriber/client
is connected) and guidance for when repeated warnings indicate a real
issue requiring error inspection.

Maintainers

If you are a maintainer of any tools in the Supabase ecosystem, you can use this site to provide documentation for the tools & libraries that you maintain.

DocSpec

We use documentation specifications which can be used to generate human-readable docs.

  • OpenAPI: for documenting API endpoints.
  • SDKSpec (custom to Supabase): for SDKs and client libraries.
  • ConfigSpec (custom to Supabase): for configuration options.
  • CLISpec (custom to Supabase): for CLI commands and usage.

The benefit of using custom specifications is that we can generate many other types from a strict schema (eg, HTML and manpages). It also means that we can switch to any documentation system we want. On this site we use Next.js, but on Supabase's official website, we use a custom React site and expose only a subset of the available API for each tool.
