I write only from my personal experience, but the following might be 
reasons that Nick recommends PostgreSQL over MySQL:

- Postgres has a history of putting SQL/database integrity first 
where MySQL emphasized speed over correctness.

- it took a long time for MySQL to add more complex transactions and 
complex queries (things got a bit better in the 5.1 iterations of MySQL)

- better support in Postgres for FOREIGN KEY constraints

- a more linear scaling (the performance graphs I've seen for MySQL 
tend to buckle at a certain point, while the PSQL graphs for the 
same load tend to be more linear)

- Postgres has a better track record of scaling across multiple 
processors/cores

- there are just some serious what-the-heck's in MySQL's handling of 
some edge cases regarding NULL values and dates (Feb 31st anybody). 
  There's a good compilation of them at [1].  Any one of them is 
enough to make me queasy at the idea of entrusting my data to it.

- I'm not sure I'd trust MySQL under Oracle these days having seen 
how they (don't) promote it


I do find that administering MySQL is just a bit less headache, but 
at a certain level of administration needs, Postgres offers more 
features.

Just my 0.02 of whatever your local currency is :-)
