Flink JDBC UUID – source connector

In Flink 1.15, I want to read a column that is typed with the Postgres UUID type (the id column).

However, this does not work; crashes with The PostgreSQL dialect doesn't support type: RAW('java.lang.String', '...') NOT NULL. How can I interpret all id results as a plain string?

• DataTypes.STRING() doesn't work
• .columnByExpression("id", "CAST(id AS VARCHAR(32))") doesn't work
• .columnByExpression("id", "\"id\"::varchar") doesn't work
