* You can either pass an existing database connection as PDO instance or
* a Doctrine DBAL Connection or a DSN string that will be used to
* lazy-connect to the database when the cache is actually used.
* When a Doctrine DBAL Connection is passed, the cache table is created
* automatically when possible. Otherwise, use the createTable() method.
* List of available options:
* * db_table: The name of the table [default: cache_items]
* * db_id_col: The column where to store the cache id [default: item_id]
* * db_data_col: The column where to store the cache data [default: item_data]
* * db_lifetime_col: The column where to store the lifetime [default: item_lifetime]
* * db_time_col: The column where to store the timestamp [default: item_time]
* * db_username: The username when lazy-connect [default: '']
* * db_password: The password when lazy-connect [default: '']
* * db_connection_options: An array of driver-specific connection options [default: []]
* @param \PDO|Connection|string $connOrDsn a \PDO or Connection instance or DSN string or null
* @throws InvalidArgumentException When first argument is not PDO nor Connection nor string
* @throws InvalidArgumentException When PDO error mode is not PDO::ERRMODE_EXCEPTION
