Looking at MySQL 8 with PostgreSQL goggles on
By Kaarel Moppel - Compare MySQL and PostgreSQL - First off - I'm not trying to kindle any flame wars here, just trying to broaden my (your) horizons a bit, gather some ideas (maybe I'm missing out on something cool, it's the most used Open Source RDBMS after all) and to somewhat compare the two despite being a difficult thing to do correctly / objectively. Also, I'm leaving aside performance comp
