It shouldn't do this. No application data should be written to /usr. Such

You should be able to do this by using debconf calls in the postrm. I don't
know whether or not you can (or should) ask questions there, but you can
retrieve answers to questions you have already asked. See the bsd-ftpd package
for an example.
