The JDBC driver is expecting a single scalar value returned from your 
function.  It retrieves the first column in the first row and detects that 
it is a varchar, not the Types.OTHER that you had registered.  You really 
don't want to use the CallableStatement interface for this operation.  Try 

Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM myfunction()");
