You tell the french guys and their couple million buildings ;-)

I'm importing brand new data, so populating the history tables is no big deal.
On second thought, I haven't implemented integrity checks yet - but they would
be only neccesary if a new way would reference an existing node, not a
placeholder ID. (Yes, I'm trusting the optimistic locking so I'm supposing
that the data that I just commited to the DB didn't get deleted so my
placeholder IDs don't get screwed around - or I could just prepare a
humongous transaction to make sure the diff upload is kind of atomic)
Anyway, I'm a MySQL guy, not a PGSQL guy. We don't need no stinkin' integrity
checks nor foreign keys here.
If I have time to code the next few months, this is gonna get fun... :-)
