Suggestion: add an EXPLAIN method to t3lib_db and extend the method for the 
various DB handlers in DBAL. IIRC there is already some stub code somewhere 
in DBAL (though not in t3lib_db).

Note on Oracle: AFAIK the standard procedure is to use a certain table for 
EXPLAINing. I think the DBAL can assume this name. If you're ambitiuos you 
can make this configurable, but DBAL is for pros only that know what 
they're into ;-)
