Yanquan Lv updated FLINK-39294:
-------------------------------
Description:
The PR FLINK-38959[postgres] Update split state's table schemas info and infer
schema change event based on pgoutput plugin's relation message (#4316)
introduced a new configuration option for the PostgreSQL CDC connector.
New Configuration Option:
|Option|Type|Default|Description|
|schema.change.enabled|Boolean|false|Whether to enable schema change event
capture. When enabled, the connector will capture schema change events from the
pgoutput plugin's relation messages and update the table schema accordingly.|
What needs to be documented:
1. Add the new `schema.change.enabled` option to the PostgreSQL CDC connector
configuration table in the documentation.
2. Explain the purpose of this option: it allows the connector to capture and
handle DDL changes (e.g., `ALTER TABLE ADD COLUMN`) during incremental reading
phase by leveraging the pgoutput plugin's relation messages.
3. Note that this feature is marked as `@Experimental`.
