Their methodology is here: https://db-engines.com/en/ranking_definition https://db-engines.com/en/ranking_definition A lot of it is highly suspect in my opinion. First off, they don't specifically say how they consider Postgres for some of their factors. E.g. in their "Mentions on system websites" section they say > In order to count only relevant results, we are searching for <system name> together with the term database, e.g. "Oracle" and "database". But I'd expect Postgres mentions to be split a lot between "Postgres" and "Postgresql", and it's not clear they included both terms. More importantly, the vast majority of these factors are trailing indicators. Even if no same person would use Oracle for a new installation, their existing giant (and very difficult to migrate) install base means you'll see tons of Oracle mentions in LinkedIn profiles and job reqs for decades.
