Listens for incremental changes in a PostgreSQL database and triggers feature change actions.
This extension can be useful when the database is changed incrementally by other applications. When a change happens that is relevant for a feature type, registered actions will be triggered, for example to update the spatial extent or the feature count of an API.
You do not need this extension when changes are only made via CRUD or when a new iteration of the database is used after external updates.
