Hi!

Right. A layer of abstraction. That's just what I have: my abstraction 
does not expose any database header. Everything is hidden in a pimpl.

But how shall I implement the pimpl? It needs to "own" a database 
connection. I could write a destructor that closes the connection. But I 
don't bother. I try to avoid writing any destructor. I stick to existant 
RAII classes. So I use a shared_ptr with a custom deleter that closes 
the connection. Feels safe. That's what I gain. :)
