Someday... :-)

I guess support for extended INSERT should then be tackled with too...

Well, on a TYPO3 install with DBAL installed using native DB (=MySQL), 
you may monitor queries issued to the DBMS and see that the hint is 
there. When using another DBMS (such as PostgreSQL or Oracle), the hint 
is not there anymore.

Basically, without the patch and DBAL active, you get a parsing error in 
BE module of DBAL whenever you have RealURL active. Apply patch, error 
is away.

However DBAL log still shows a parsing issue because the logger (when 
activated) logs as an error a generated query that is not identical to 
its input, and as we dropped the hint part, the query is not identical. 
Query is however properly handled and sent to the DBMS.
