Dynamically Typed has this new posting with a pointer to an article making a bit of a comparison between MySQL and PostgreSQL.

PSNC have published a comparison of MySQL 4.1 and PostgreSQL 8.0.

If you're interested to know what features you're missing out on by using MySQL rather than PostgreSQL, the comparison table provides a handy summary. MySQL 5.0 (in development) is getting closer to PostgreSQL's impressive feature set, with Views and Stored Procedures on the list. According to the article, however, MySQL still beats PostgreSQL in terms of performance. Details of a number of benchmarks are given.

And, of course, there are plenty of comments to go around - what do you think on the subject? Do you have a favorite database system of the two?
