The dashboard page bootstrap data currently attempts to generate the `SELECT` statement with column name details for each table represented in the dash. This means it calls the database(s) and waits for column details prior to returning any HTML. This makes the default select_star property generate a simple `SELECT *` with no column details instead, which doesn't require interogating the DBs.
