"PostgreSQL advances to rank 4 in DB-Engines Ranking"

I hadn't heard of this site before: http://db-engines.com/en/ but it seems they

popularity, frequency of job offers etc. It seems PostgreSQL has just overtaken
MS Access to climb to 4th place:

The methodology looks like it produces a useful overview of general trends,
although with this kind of thing I guess the actual "scores" produced are
pretty meaningless.
