In issue #2354 it is discussed multiple times that displaying the generated SQL might be interesting too. It seems like this feature was in the end not implemented.

I unterstand that there are other ways to retrieve the SQL query (for example through logs and using EXPLAIN VERBOSE to get the query ID to make sure to find it easily...

However, any explain plan returned through the plan accept header implemented is always going to be easier to understand, judge and also act upon with the SQL query present in the same data without having to implement extra steps which enable logging queries. It seems a lot more efficient to have the option to just return the SQL query right before the plan in the same reply?

I understand security considerations need to be taken, but this could be implemented via an extra config as db-allow-generated-sql or db-allow-plan-sql if it is only usable in combination with plan.
