It was only taking about 7 seconds for me on an empty database, but if
it's not useful I'll go back to the original output format.

OK. I'll leave as is.

Looks plausible. But I guess it will be easier to tell once it produces
results in the same format as before. I'll make the changes and send it
in to patches.
