I moved the SQLite and Postgres subprocess implementations (written in
C) under the Lisp Union organization:
<https://github.com/lispunion/database-subprocess>. Yesterday I wrote
some code to talk to them from the CLISP implementation of Common Lisp,
which required zero changes to the subprocesses :)

The subprocess interface is getting complex enough, and needs to be
integrated to the Scheme DB API, that it'd be nice to start drafting a
specification document for it somewhere.

Harold, what do you think would be a good place to keep that spec in the
drafting phase? I don't really care much, so long as it's easy to
change. E.g. a GitHub Wiki or would be fine. Or a repo with a text file.
