Today, it is very difficult to troubleshoot issues when their cause is related to the use of a non-default server parameter or values.

It would be useful to have an additional log line highlighting everything non-default. Just by looking at this line can give us a hint where the issue might be originating.

Today, it is also not possible to understand if currently-printed values are default or not. One would have to go to documentation and validate each and every value to understand this.

This would also help to avoid issues when some previously used parameter/value is being unintentionally dragged into the newer version.
