Is this really true? I'll freely admit that I have only cursory
experience with RDBMSes. However, with the current apt cache code,
lookups are basically a pointer dereference (and maybe a page fault).
I don't see how an RDBMS could possibly improve on that. There might be
other benefits to an RDBMS, but I'm not convinced this is one.

One benefit which I didn't see listed in your mail is that it might
become easier to augment the cache with more information; a great deal
of slowness in aptitude's startup, for instance, comes from reading
tables that aren't included in apt's global cache.
