Returns:

a CompletableFutures.SQLResult containing an XGConnection

hint_bypassLoadBalancerOnHandshakeOnly - set to true to disable redirect on connect

Returns:

a new XGConnection object based on the current connection, with the specified properties

Throws:

SQLException - if there is an error creating the new connection
