You'll likely need to modify OGR to log this level of detail. In
general, this type of logging is done by the 'server' in DB
environments: Since SQLIte doesn't *have* a server, I don't think
there's any way to do this external to OGR, and I don't believe that
it's an existing feature of the OGR sqlite driver.

In any case, MapServer is the wrong list for this: gdal-dev is probably
the right place to go.
