Ok, I think I found the problem. It's quite simple too.
My zones are not changing very often. So, after my re-setup of NS2, and
restart master-powerdns, the "notified-serial" and the first digit
serial of "SOA" where the same. If notified-serial is smaller than SOA,
only then PowerDNS will do an AXFR.
So, indeed, after setting up a new/extra nameserver, to start the
transfer, one should just run SQL:
UPDATE domains set notified_serial=0
and make sure that every SOA record is NOT 0. Then, PowerDNS will start
notifying slaves.
I think it might be a good idea for future versions of PowerDNS, to
"force" updating all slaves when PowerDNS is started.

After stopping Pdns, setting notified serial to 0, and starting powerdns
in monitor mode, I immediately see an AXFR for this domain come up, and
it gets transferred indeed.
Other solution I found:
Lower the first digit of the SOA field, then start Powerdns. I changed
it from 2010080500 to 1010080500. Now also a transfer took place.
Adding the 10800 3600 604800 3600 expire values does not seem to do
anything (except after also lowering the first number). Or do I have to
wait (long) for that? That would not be right, if it was the case.
However, why does PowerDNS notifies my slave if I lower either the first
SOA number, or set the notified serial to 0?

For the mailing list archive, I also present the data for one domain
here:
While i can not find anything that looks obviously wrong to me, you
might try the following:
- setting domains.notified_serial to 0 or 1.
- providing a full set of ttls in the SOA record such as

Also what does your daemon.log - or wherever pdns logs to - say about
this?
