Just checking the dependencies and sizes on woody, neither libgda nor
unixodbc are more leightweight than linking directly against mysql
and pgsql *at* the *same* *time*.

gda looks small but its interlibrary dependencies on woody are
completely over the top (complete GNOME), the version in sid is iirc
sane, but still pulls in libglib1.2, libxml1 and libxslt1, which makes
it bigger than libmysqlclient+libpq.

The crux of the whole matter with respect to exim is that it not
optimized for binary redistribution (else it would dlopen the lookup
modules) and that its *sql lookup methods are a lot older than gda and
_perhaps_ unixobdc.

Imho switching from direct lookups to one of these wrapper libraries
isn't in the responsibilty of the debian maintainer _and_ I do not
think a paragraph in policy would buy anything (policy is no stick to
beat with), submitting patches to upstream might work.
