/**
* Constructor.
*
* 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.
*
* 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: array()]
*
* @param \PDO|Connection|string $connOrDsn A \PDO or Connection instance or DSN string or null
* @param string $namespace
* @param int $defaultLifetime
* @param array $options An associative array of options
*
* @throws InvalidArgumentException When first argument is not PDO nor Connection nor string
* @throws InvalidArgumentException When PDO error mode is not PDO::ERRMODE_EXCEPTION
* @throws InvalidArgumentException When namespace contains invalid characters
