* @param {Boolean} [options.omitNull=false] A flag that defines if null values should be passed to SQL queries or not.
* @param {Boolean} [options.native=false] A flag that defines if native library shall be used or not. Currently only has an effect for postgres
* @param {Boolean} [options.replication=false] Use read / write replication. To enable replication, pass an object, with two properties, read and write. Write should be an object (a single server for handling writes), and read an array of object (several servers to handle reads). Each read/write server can have the following properties: `host`, `port`, `username`, `password`, `database`
* @param {Object} [options.pool={}] Should sequelize use a connection pool. Default is true
* @param {Integer} [options.pool.max] Maximum number of connection in pool. Default is 5
* @param {Integer} [options.pool.min] Minimum number of connection in pool. Default is 0
* @param {Integer} [options.pool.idle] The maximum time, in milliseconds, that a connection can be idle before being released
* @param {Integer} [options.pool.acquire] The maximum time, in milliseconds, that pool will try to get connection before throwing error
* @param {Object} [options.pool] sequelize connection pool configuration
* @param {Integer} [options.pool.max=5] Maximum number of connection in pool
* @param {Integer} [options.pool.min=0] Minimum number of connection in pool
* @param {Integer} [options.pool.idle=10000] The maximum time, in milliseconds, that a connection can be idle before being released
* @param {Integer} [options.pool.acquire=10000] The maximum time, in milliseconds, that pool will try to get connection before throwing error
* @param {Integer} [options.pool.evict=60000] The time interval, in milliseconds, for evicting stale connections. Set it to 0 to disable this feature.
* @param {Boolean} [options.pool.handleDisconnects=true] Controls if pool should handle connection disconnect automatically without throwing errors
* @param {Function} [options.pool.validate] A function that validates a connection. Called with client. The default function checks that client is an object, and that its state is not disconnected
* @param {Integer} [options.pool.evict] The time interval, in milliseconds, for evicting stale connections. The default value is 0, which disables this feature.
* @param {Boolean} [options.quoteIdentifiers=true] Set to `false` to make table names and attributes case-insensitive on Postgres and skip double quoting of them. WARNING: Setting this to false may expose vulnerabilities and is not reccomended!
* @param {String} [options.transactionType='DEFERRED'] Set the default transaction type. See `Sequelize.Transaction.TYPES` for possible options. Sqlite only.
* @param {String} [options.isolationLevel] Set the default transaction isolation level. See `Sequelize.Transaction.ISOLATION_LEVELS` for possible options.
