The original design intention was that rm_desc should not attempt to
print any such data, but obviously some folks didn't get the word.
The question is whether we're willing to add a lot of cycles to
XLOG_DEBUG mode in order to make the full record available for printing
purposes.  Not sure if it's a good tradeoff or not.
