You're right, I've emphasized that up near the top, thanks.

I have downloaded a copy and given it a beginning look. I'm new to parsing things of that magnitude; my first thought was to use the full history file for creations/modifications/deletions on nodes and add that to what I'm doing already for ways on the osm2pgsql tables. Does that sound reasonable?

I'll check out your parser; what kinds of metrics does it produce?
