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

Hi [~jark]

I don't understand why I should call this function in the SQL as the output field ?

Does this function is ANSI SQL, Flink SQL or even postgres?

> Currently, JDBCTypeUtil used by JDBCAppendTableSinkBuilder dones't support UUID types with java.util.UUID in Java.
