I am going to start working on it. I am concerned it is a big job.
I will post questions as I find them, and the one below is a good one.
It is a big question, at least it's the main stumbling block I had, and
it's the one that kept my work from being integrated into 8.0 (which
side stepped the issue by using libpq to connect to the server to fire
off commands).

I just realized that the non-standard backend can't execute any SQL command.
If so, how would the background pg_autovacuum do "vacuum"? It could be
forked more like a standard backend, but this is obviously not a good idea,
since we don't know which database this process will sit on.
A possible solution is that backgroud pg_autovacuum could fork another
process to connect to postmaster as an ordinary backend each time it feels
that a "vacuum" is needed.
