Workaround to PreparedStatement.setNull()?

Hi!

I’m trying to make

java.sql.PreparedStatement.setNull(i, java.sql.Types.INTEGER);

But i get:

org.postgresql.util.PSQLException: ERROR: column “number_column” is of type integer but expression is of type character varying
Hint: You will need to rewrite or cast the expression.

I have Postgresql 8.4 and postgresql-jdbc-8.4-703.

Does anyone know about a workaround to this?

Thanks a lot!
