Updated patch attached. The latest version is always in the git repo.
http://repo.or.cz/w/pgsql-fdw.git   (branch: fdw)
I'm developing the patch on postgres' git repo. So, regression test
for dblink might fail because of out-of-sync issue between cvs and git.

Sure. I'll start to write documentation when we agree the design of FDW.

Sure, but I'm thinking that it will be improved after libpq supports
protocol-level cursor. The libpq improvement will be applied
much more applications including postgresql_fdw.
