What's dbupgrade()? I can find only a reference to a program called dbupgrade, and I don't have one on my computer.

Its part of the sleepycat database API to upgrade from old formats to new. When you build BerkeleyDB it does create a standalone command line utility that'll call the function for you but its also available thru the C (and python) api. See the bsddb.db.DB.upgrade() method.
