No kidding. If you really can avoid all the caveats on MySQL, installing of PostgreSQL is nothing hard. It's just your belief that you can avoid all that caveats.
Also, why don't you use Heroku PostgreSQL app which is just one-click starting self-contained app?
If you're on FreeBSD/Linux desktop, how can you fail to install? Of course it doesn't work just right after install, and it needs manual initial configuration for security. But that shouldn't be hard to any Unix family server developer.
If you're on Windows desktop, why don't you run your own FreeBSD/Linux server VM instance for your own development?
If you're using Windows server… with MySQL… Hmm then I am sorry. I have no more idea.
