## 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.
