Nice work!

Although not sure if we should focus directly on sqlite4 (could be
optional with a configure flag and a subtree [until stable], sqlite3
supported over depends).

Also i personally would recommend to not implement it as a
replacement, instead, support multiple backends (wrapper header /
different wrapper implementations [leveldb / sqlite3 / sqlite4]). But
– agreed – should not be the focus, but a nice additional flexibility
if it not require much more work.
And – in theory – multiple database back-ends would allow migration.

Before investigating to deep, i think we need a dbwrapper bench tool
that represents our needs and our style how we hit the database.
Gavins recently added bench target / bench environment could be used
for that.
