FWIW, I think they're highly relevant, because they put a date on that text. I've not gone through that README lately, but I wouldn't be surprised if it's largely obsolete --- it hasn't been maintained in any meaningful way since Vadim wrote it. Without the headers, a reader would have no warning of that. What really ought to happen, likely, is for somebody to extract whatever is still useful there into a new(?) section in the parent directory's README. regards, tom lane
