There is a function to query the backend to see what features it 
supports, but prepared statements is not in that list.  Also, if we 
require prepared statements, that might cut out the sqlite backend 
because a libgda modification to use it might not propagate out far 
enough.  I know Derek wants to see the xml gnucash file replaced by a 
sqlite db, so we need to be really sure it is unusable before we 
disqualify it.
