I'm actually leaving this list but I can answer this question. Our results
were with a single user and we were running Inodb. We were running on
RedHat 8.0 / 9.0 with vanilla linux settings.

I'm curious what the usage was. How many concurrent processes were
performing the complex queries? I've heard that Postgres does better when
the number of concurrent users is high and MySQL does better when the number
is low. I have no idea if that is true or not.
