Unfortunately adding Postgres support isn't as easy as switching the PDO driver, because Postgres has significantly different syntax from MySQL (mostly around quote styles, e.g. "foo" for table names and 'foo' for strings, whereas MySQL uses "foo" or 'foo' for strings and `foo` for table names). It would take adding a new file for Postgres support similar to the MySQL file (https://github.com/idno/idno/blob/b748d7765e2a0999fe2bf90f79a816aede366a74/Idno/Data/MySQL.php) you found.
