1. The big advantage MySQL had, which is rapidly fading, is that it was easily available on cPanel and Plesk hosts, which postgres was not. There was a time that that was 95% of non-expensive hosting.
Back in the era when PHP was everything, that was a big deal. Now, not so much.
If you have to support self-install people on cheap hosting, it can still matter, but that is a vanishing goal these days
2. I haven't found any benefits in MySQL, and I wish I could switch to Postgres.
