Well, I don't know if I still count as one of the `dpkg team' but I
think this is a terrible idea for lots of reasons.  dpkg needs to be
very reliable; its databases must not get corrupted even under
situations of stress.  It is also very useful that the databases are
tractable with normal tools.  dpkg is very close to the bottom of the
application stack; making it depend on a big and complex library like
a SQL engine is a bad idea.

In practice I think the problem isn't that the *.list files are too
inefficient an on-disk representation.  I have a number of machines
with small CPUs and little memory and they don't have a difficulty

But there are some significant performance problems elsewhere:
 * The status and available file parser is too slow.  I think this
   needs some optimisation work.
 * We still need the `smallmem' in-memory model for the file list
   data (removed by Adam Heath while he was ripping out my nicely
   simple counting allocator and replacing it with use of glibc
