the re module in pypy is not a c extension, so yes :)

there is a ctypes driver for sqllite and mysql (this last one being
used in quora). There is a postgresql driver also but this one is a
little harder to get going (it needs to be translated with the pypy
interpreter) but there are pure python ones and they might be pretty
fast.

this question I will leave for amaury to respond.
