Good work. One question though, temporary tables. Currently there no way to get a consistant view of a temporary table from another process. You probably have to avoid shipping off non-immutable function calls. Is it possible to deadlock (don't see how, but I may not be looking hard enough). Hardest work would be finding what can be safely farmed off. Nice work though, I hadn't thought of this approach.
