I don't have sufficient experience with SQL to be able to
really make a judgement here, but is there a case for a std.sql
or std.db that would provide a uniform D interface to the
arbitrary DB of choice?
Perhaps better as something in Deimos rather than Phobos, as I
imagine it would bring in a bunch of external dependencies that
the standard library shouldn't really have. Am I right that
there's something in Adam Ruppe's web modules that's heading in
this direction?
There was a std.database proposal from Steve Teale, but it
appears to have died.

It could work like in other languages with OO support.
Everything is interface based and it is up to the respective
driver to provide proper implementations. Those implementations
can be provided either as static or dynamic libraries.
The important thing are interfaces, as such you're not bringing
external dependencies. Unless the D community decides to have the
drivers as part of the language (comes with batteries kind of
thing).
