Database corruption violate I (Integrety) and D (Durability). So you
can't have a database providing ACID without protecting against database
corruption. Consistency is actually the second letter of ACID.

That said, there are limits. Enough issues that can corrupt a sqlite
database can also corrupt the current pkgdb tree. In fact, a number of
issues are less likely to hit sqlite. It doesn't mean that either is
perfect.
