These are all covered in more detail that you probably want at http://www.postgresql.org/docs/techdocs.83
The quick summary is that MySQL is very fast when using its MyISAM engine, which is prone to many data integrity issues. If you switch to the more reliable InnoDB engine most of the performance advantage MySQL might have goes away. There are also a couple of areas where PostgreSQL is almost always faster: complex joins and scalability under a heavy transaction load are two examples.
3] community support
It's not unheard of for someone who is really having a problem that looks like a database bug to get one of the core PostgreSQL contributors poking at their box to figure out what's going on. Meanwhile, MySQL can't even get enough resources together to get their new version out the door (V5.1 has been lingering around since November of 2005), so there's little developer capacity to spare to help users like the support you find on the mailing lists here. I think if you poke around a bit you'll discover the MySQL community has been rather unhappy with the number of bugs in MySQL 5.0 and 5.1. A good intro is http://www.mysqlperformanceblog.com/2007/10/04/mysql-quality-of-old-and-new-features/
5] ease of use
MySQL has more applications aimed at making it easier to use the database floating around. If all you want to build is a simple system, it's probably got an edge there. Whether that's still true if you're building something complicated enough that you can take advantage of some of the more powerful PostgreSQL features MySQL doesn't have is certainly debatable.
