[support] using two different database type

Yes, this is most unfortunate.  I've an idea of how to fix it but I 
won't even begin until after the PDO patch is in.

What an odd sentence.  Drupal doesn't need to use classes and 
instantiation to resolve this bit of hardship.  It just needs to use 
the database type to resolve which function to hook from the global 
function name.  So I call db_query() in my module but that will call 
db_query_mysql() or db_query_pgsql() dependent on the type of the DB 
active at the time.  Currently the design declares the same db_query() 
function within more than one file which is really sad.
