That was my biggest gripe with it - at least back in the day. Back then it really felt like MySQL vs Postgres was a trade-off between 'easy but no guarantees on data integrity' and 'correct but operationally harder to manage'. The gap has for sure closed in many areas but I still feel safer with Postgres today because there's been little reason for me to try MySQL again.
