Description

For replication mode, the schema can change, and the transformation rules might need to change accordingly. Have a way of supporting automatic reloads to avoid having to stop the process each time a new sensitive column is added.

Contributor guide

Research direction
Investigate how pgstream currently handles transformation rules and design a mechanism to automatically reload them when schema changes are detected. Look into using PostgreSQL NOTIFY or a background watcher to trigger reloads.
