Well. If such a mode ever becomes available I'll be looking into how to
make sure it never gets turned on. My mind is currently boggling at the
number of things it would break.

A transaction is either committed as a whole, without errors, or not at
all. If you want to do a savepoint after each statement, go right
ahead, nothing is stopping you. I just don't think making it any kind
of default is a very good idea...
