Could be that the database is not being vacuumed.
Sqlite is used and only implementation differs, as I know.
I assume next version would have better handling, if you
upgraded and experienced the same problem.
Regarding one file db, sqlite proved to be stable and works
fine on at least one gadget I own. No reason to change it
to something more advanced and much bigger.
