I'm open to all suggestions. However, I'm not pushing for my stuff to
be included in the main trunk; I'm totally happy to live as a diff,
so to speak.

Still, my (ugly) hacks may help with insights around making the
(D)SQL compiler more modular / plugable; Another project which may
aid generating such insight is thinking through how to build the
engine and gpre of a single SQL compiler codebase. Generating
requests instead of blr for dynamic DML has been advocated by Jim for
a long time.
