 The driver uses a connection pool at all times, by default it creates and frees connections automatically. It's safe for concurrent use by multiple goroutines.
 
-To configure the connection pool `MaxIdle`, `MaxOpen` and `IdleTimeout` can be specified during connection. If you wish to change the value of `MaxIdle` or `MaxOpen` during runtime then the functions `SetMaxIdleConns` and `SetMaxOpenConns` can be used.
