I'd be quite happy with SOAP. We can make SOAP::Lite an optional load
module, so if you don't want to run patches you don't need to have the
module available.

This reasoning seems unsafe. I am not prepared to test arbitrary patches
on my machine - that seems like a perfect recipe for a trojan horse. I
want to know that they have been vetted by someone I trust. That means
that in order to get into the feed in the first place there has to be a
group of trusted submitters. Obviously, current postgres core committers
should be in that group, and I can think of maybe 5 or 6 other people
that could easily be on it. Perhaps we should leave the selection to the
core team.

That's an excellent point; I didn't think of the trojan horse
scenario.  What do you think about setting up the buildfarm clients
with the users they are willing to test patches for, as opposed to
having the patch system track who is are trusted users?  My thoughts
are the former is easier to implement and that it allows anyone to use
the buildfarm to test a patch for anyone, well each buildfarm client
user permitting.
