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.
