prepared statement

[rossetti]

The documentation appears to indicate that prepared statements are supported, but I get the following when trying to use prepared statements (v1.1.3)

java.sql.SQLFeatureNotSupportedException: prepareStatement

I think that it is related to the following:

con.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS)

My guess is that DuckDb is not supporting the RETURN_GENERATED_KEYS option. If that is the case, then the documentation should indicate this lack of support for a basic JDBC functionality or if it is supported then it is not working.
