Going back to the late 90s, early 00s there was this idea that MySQL is fast and Postgres is slow. It's not accurate or even relevant anymore because MyISAM is how MySQL got a reputation for being fast, but that's no longer the default table type and people know by now that it's not a good default practice. And Postgres has improved significantly. And proper index use isn't an arcane art anymore. It's been many years since this has been accurate and also many years since this was as widely believed as the author of this article believes. Also, while speed no longer differentiates these databases, it should rarely if ever have been the primary factor in choosing one. (Or in avoiding Postgres in general.)
