Well, now that you mention it, that code is utterly, completely broken,
and always has been. It's passing only the first rdata-chunk of the WAL
record to the print routine :-(
AFAICS the only way to fix it would be to allocate some workspace and
assemble the chunks of the record into that. Doubtful that it's worth
it --- I'd be inclined to just remove the code instead.
