We had this topic a dozen times (please read the archives[1], guys!),
and I believe that the consensus was that multiple RDBMS support is not
a good idea, mostly because of the fact that it is  preferable to use
the advantages of certain MySQL features over portability to DB systems
that don't meet most of the target audience anyway. Another fact is that
it would also requite plugin authors to write cross platform plugins.
This is not only very hard, because you can't expect them to test on all
major DB systems, but you would again dramatically limit possibilities
(like e.g. using FULLTEXT indices) where it's actually not required.

I'd propose, if you bring this topic up again, you would have to read
the archives (and refer to them, where necessary), and you would have to
bring new and very good arguments for multiple RDBMS support.
