How is it configured to not log that info (since it is supposed to be expensive)?
Look at the code in DBAppender. It should make it clear.
Also am I curious why you write "?" instead of just leaving it null.
That's because the locationInfo fiels in LoggingEvent is initialized lazily. If it's null and LocationEvent.getLocationInfo is invoked, then caller's location info will be extracted. By initializing it to a non-null value when persisting the event, we are making sure that it won't be mistakenly initialized for a "cold" event. (A cold event is an event which has been already retrieved from the db or some other persistent medium or deserialized from the network.)
Does that make sense?

Indeed. If no location info is desired or unavailable, it will still be written as "?".
