Just checking in - I went ahead and set my master up to use pgsql for the 
backend and notifies and transfers are working fine.  The slave is running 
sqlite and it's able to handle the incoming transfer without issue.  Not 
sure if that helps or not, but I can tell you both servers are running the 
same build of PowerDNS and SQLite.

Logs of the successful notify and axfr on the sqlite slave:
