Was this attempting to do each update in a separate transaction?
If so, that is certainly expected, with whatever disk based transactional
database you use. With innodb, you could hack around it by configuring
innodb not to flush its log to disk at every transaction, obviously at
the risk of loosing data if something crashes.
From what I have seen, I would expect innodb's multiversioning to work
better for the use you describe than postgresql's due how it implements
undo logs for updates. However, there could well be other differences
that could make postgresql work better for your application depending on
exactly what issues you are seeing.
