------------------------------------------

             Summary: Properly set constraints (PK and UNIQUE)
                 Key: FLINK-17356
                 URL: https://issues.apache.org/jira/browse/FLINK-17356
             Project: Flink
          Issue Type: Sub-task
          Components: Connectors / JDBC
            Reporter: Flavio Pompermaier


At the moment the PostgresCatalog does not create field constraints (at the moment there's only UNIQUE and  PRIMARY_KEY in the TableSchema..could it worth to add also NOT_NULL?)
