JDBCAppendTableSink on Data stream

[Chirag Dewan]

Hi,
In the documentation, the JDBC sink is mentioned as a source on Table 
API/stream. 
Can I use the same sink with a Data stream as well?
My use case is to read the data from Kafka and send the data to Postgres.
I was also hoping to achieve Exactly-Once since these will mainly be Idempotent 
writes on a table.
Any help much appreciated. 
Thanks,
Chirag
