Represent a drop operator class statement (PostgreSQL)

let mut issues = Issues::new(sql);
let mut stmts = parse_statements(sql, &mut issues, &options);
let drop: DropOperatorClass = match stmts.pop() {

    _ => panic!("We should get a drop operator class statement")
};
assert!(drop.class.identifier.as_str() == "myclass");
