请问postgresql cdc 怎么设置单独的增量模式呀，debezium.snapshot.mo
同问，这几个配置都不生效
Specifies the criteria for performing a snapshot when the connector starts:
initial - The connector performs a snapshot only when no offsets have been recorded for the logical server name.
always - The connector performs a snapshot each time the connector starts.
never - The connector never performs snapshots. When a connector is configured this way, its behavior when it starts is as follows. If there is a previously stored LSN in the Kafka offsets topic, the connector continues streaming changes from that position. If no LSN has been stored, the connector starts streaming changes from the point in time when the PostgreSQL logical replication slot was created on the server. The never snapshot mode is useful only when you know all data of interest is still reflected in the WAL.
initial_only - The connector performs an initial snapshot and then stops, without processing any subsequent changes.
exported - The connector performs a snapshot based on the point in time when the replication slot was created. This is an excellent way to perform the snapshot in a lock-free way.
custom - The connector performs a snapshot according to the setting for the snapshot.custom.class property, which is a custom implementation of the io.debezium.connector.postgresql.spi.Snapshotter interface.
