In an earlier post I made, I described how to manually create the SQL schema, because it didn’t itself. When I installed Power DNS 3.1-4 on a Raspberry Pi, I noticed it had created the scheme itself this time. However, it did not make the foreign key constraints. This is dumb. I regularly need to remove domains from the DB and I don’t want stale or incorrect references as a result.

To create them by hand:

alter table records add foreign key (domain_id) references domains(id) on delete cascade;
alter table cryptokeys add foreign key (domain_id) references domains(id) on delete cascade;
alter table domainmetadata add foreign key (domain_id) references domains(id) on delete cascade;

It must be a bug that this was omitted, because I got the original scheme from the PowerDNS website. Question is, is this a bug in the Rasbian/Debian package, or in PowerDNS?
