It's not really "done" --- the ideas in the TODO file about using more
intelligent compression methods are still on the table.  All I've done
is to nab some very low-hanging fruit.

There's also the whole business of removing page images entirely from
archived WAL files; this didn't address that at all.

Yea, I am guessing that is as far as we want to go with compressing page
images for a while.  I will just remove the TODO item rather than mark
it as done.

Right, I kept that in the TODO.detail and on the TODO list.
