Not shure. Osmosis should work with foreign keys, so this may be a bug.

I would however recommend loading the data into a database without any
indexes or foreign keys and then recreate them.


This is much faster for that size. The reason is that INSERTing
otherwise writes the data _and_ the indexes. This causes the heads to
move back and forth (unless you have seperate disks for the data and all
its indexes), which means a major slowdown.

Sorry, probably you can't.
