### Search before asking - [X] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened When synchronizing data with PostgreSQL CDC, if the field type is varchar (2) and the value is null, the insertion statement becomes' NULL:: character varying ' ### SeaTunnel Version 2.3.4 ### SeaTunnel Config ```conf env { # You can set engine configuration here execution.parallelism = 1 job.mode = "STREAMING" checkpoint.interval = 5000 read_limit.bytes_per_second=7000000 read_limit.rows_per_second=400 } source { Postgres-CDC { base-url = "jdbc:postgresql://xxxx:5432/tenant_xj" username = "xxxx" password = "xxxx" database-names = "tenant_xj" schema-names = "public"
