Yes, be default postfix-policyd won't work on debian.
Since the installer script doesn't provide sql root password when debian asks for it.
Easy fix for it will be just to reinstall it.
So you can safely run:
aptitude purge postfix-policyd
aptitude install postfix-policyd
if you getting
postfix-policyd: fatal: didn't find priority 'LOG_IFOO', exiting
update /etc/postfix-policyd.conf
SYSLOG_FACILITY="LOG_MAIL|LOG_INFO"
Hope that will help
