As discussed in [Pdns-users] Question regarding DNSSEC RRSIG, a pdns 3.1 slave running mysql may in some situations return bogus NSECs.

It also contains hacky fixes for gmysql and gpgsql. Especially the gpgsql fix is unsuitable as it requires dropping/restoring whole databases. The gmysql-fix is easier to apply to current setups but it needs a little more love.
