As someone who has worked with Oracle, mssql and postgres: If it gets complex I tend to use a search engine for oracle or mssql, for postgres I go straight to their official docs. Postgres documentation quality is very good and honest. Also, the number of postgres weird edge cases and ad hoc hacks in SQL feels lower. If my experience generalizes, this ranking will score you higher the more support you need. Well working software generates less noise and is measured as less popular as a result.
