Moodle tables. ie user -> userid in many tables, plus in user_students start -> starttime and end -> endtime I've just done all this as carefully as I could ... I don't think I missed anything but it's pretty intensive work and I'd be fooling myself if I didn't think I'd missed a couple. Note that this version should pretty much be able to bootstrap itself using PostgreSQL now ... but this is untested
