i think they would not be very receptive to the idea, as i think
it would work against the way the entire reasonable stable and
explainable interrelatinships work with the dpkg/apt tools...
my guess is that their response would be "either you need the
package or you don't.  if you can live without the package
then it should be a Recommends/Suggests."

i think a rather simple way to help with this is have a chunk
of code in the postinst script such that if the user selects
localhost it checks for being able to access the database,
or at least that the server is in the PATH.  if not, it
could issue a stern warning like:

  "Warning: $dbtype server not found. Abort installation?
   .
   You've chosen to install the database on the local host, but there
   doesn't seem to be a database server running.  If you have a
   database server installed locally on your system outside of the
   debian package management system, you can safely ignore this message,
   but otherwise if you expect this package to work out of the box you
   should stop now and install $dbtype_server."
