BTW, has anyone got an opinion about whether to stick the full fix into
9.4? The argument for, of course, is that we'd get the full fix out to
the public a year sooner. The argument against is that someone might
have already done compatibility testing of their application against
9.4 betas, and then get blindsided if we change this before release.

I'm inclined to think that since we expect json/jsonb usage to really
take off with 9.4, it might be better if we get row_to_json behaving
unsurprisingly now. But I'm not dead set on it.
