Instead of trying to make db global, dbconnect() can return the db object:
if dbtype == "sqlite":
conn = sqlite3.connect(cstr)
elif dbtype == "postgres":
conn = psycopg2.connect(cstr)
db = dbconnect(dbtype)
print "updated " + dbtype
It would probably be even better to return conn, as that would allow
updatedb() to call conn.disconnect().
