Here the author. I understand your points, I wrote a bit about my personal motivation behind this project.

I also wrote within the readme about why wrote the project (context+goals), https://github.com/rach/pome#why-building-pome
This project is not aimed to replace more advanced tool like collectd but to offer a basic all-in-one solution. I'm also not planning to support huge database for the scaling problem that you highlight.
Trying to offer something easy without RDD store constraint for people who right now doesn't monitor their db.
I hope this make the goals behind the project more clear.
There is also a patch to bring columnar storage into 9.6 (coming from the Axle project, EU founded). Definitively the gap becoming smaller but CitusDB is also having a lot of the glue built already with easy sharding (pg_shard) ..
It's an exciting time for PostgreSQL!
From what I've been reading on the on the development of 9.6 (https://commitfest.postgresql.org/), we may only see parallel seq scan and ordering coming to 9.6. They added the foundation to make more thing parallele but I don't think that we can hope to see parallel aggregation coming into 9.6
I had a similar experience. And event after living in a UK/US for 6y and my partner being a native english speaker, sometimes I struggle. One other frustration that I had, when you have to argue for your case. If you have to justify a solution against a native english speaker that can create some frustration as finding the right wording for the arguments can be sometimes a challenge.
Coming from Belgium, petke is also right about the influence of small language community. In example, in the flamish part (where belgian speak dutch), a lot of tv program and cinema is dub from english and even some cartoon. Where in the Walloons part (where belgian speak only french), we have access to the big tv network from France so we never watch anything in English.
But I remember reading that different languages use different sounds spectrum and hearing/understanding languages outside your spectrum is harder. Some languages have overlapping sounds spectrum which make learning different language easier. Now you have also the languages sharing the same roots and as you said somebody who know a germanic language then will have easier to guess/learn new vocabulary.
"Batteries Not Included" in this article refers to the fact that PostgreSQL doesn't offer any built-in solution yet to do HA (automatic fail-over) and you have to depend of 3rd party solution.
