there are many possibilties to do this.
On of them was already mentioned: mysql replication. This is maybe the
best way.

Another is to write a small shellscript, that runs every 5 minutes with
cron and do the following:

for i in `mysql databasename -hhostname -u username -e "SELECT * from
domains"` ; do pdns_control notify $i ; done

The last method is not very good and with many domains your database and
powerdns have every 5 minutes a lot of work - but it works with less

Another way is to use the same Database for all 3 Nameservers. But THIS
is the worst method for your Problem - if the Database is off, you have
some serious problems.
