I'm just looking at this patch, and I agree, it should be testable. I'm
wondering if it wouldn't be a good idea to have a module or set of
modules for demonstrating and testing bits of the API that we expose.
src/test/api or something similar? I'm not sure how we'd automate a test
for this case, though. I guess we could use something like pg_logforward
and have a UDP receiver catch the messages and write them to a file.
Something like that should be possible to rig up in Perl. But all that
seems a lot of work at this stage of the game. So the question is do we
want to commit this patch without it?
