 Oh, the sql tests were 'hiding' in test resources!  That's why I ignored
 them earlier.  The correct Metrics' environment expects these in
 `test/sql`, which can be done now or when this module is refactored.

 Hmm, debian stretch is the current stable and has
 [https://packages.debian.org/stretch/postgresql 9.6]
 and provides
 9.4].  Unless our server gets the current stable soon, it might need the
 backported postgres.

 What version is on the old sqeeze?

 > True, we could add indexes later. Though I didn't spot any obviously
 missing indexes in my tests so far. The largest amount of data I imported
 was 2 years, but I didn't test continuous updates after that. I guess
 we'll learn.

 I'm not entirely happy with the JUnit/pgTAP mix here. But I hope that

 Well, I think it's ok to go.

 Could you change the module path from `modules/servers-ipv6` to
 `modules/ipv6servers` and the package name from `serversipv6` to
 `ipv6servers` before I review the java code?
