Bug introduced by
It seems like $password can also be of type string; however, parameter $passwd of Crate\PDO\PDOCrateDB::__construct() does only seem to accept null, maybe add an additional type check? ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-type  annotation

The expression return $this->connection->exec($sql) could return the type false which is incompatible with the type-hinted return integer. Consider adding an additional type-check to rule them out.
