Review Comment:
IIUC due to technical limitations, PostgreSQL CDC does not support capturing
DDL events or emitting any schema change events. In earlier versions this
method (`includeSchemaChanges`) is presented but has no effect at all, and got
removed in https://github.com/apache/flink-cdc/pull/3464.
