ReturningClauseSupported

An actual RETURNING clause is supported in the SQL dialect of the specified database e.g. Postgres. this typically means that columns returned from Insert/Update/etc... clauses can have other database operations done on them such as arithmetic RETURNING id + 1, UDFs RETURNING udf(id) or others. In JDBC, the following is done: connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS)).
