----------------------------------
Summary: [DOC] Add documentation for PostgreSQL CDC
`schema.change.enabled` option
Key: FLINK-39294
URL: https://issues.apache.org/jira/browse/FLINK-39294
Project: Flink
Issue Type: Improvement
Components: Flink CDC
Affects Versions: cdc-3.6.0
Reporter: Yanquan Lv
*{*}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`.
