I used to be really, really into MySQL, but since getting into Postgres I've come around to preferring it. They're both good.. but anecdotally Postgres is more developer friendly and generally easier to deal with in production. Postgres also comes with features that blow MySQL away in terms of flexibility and letting you do truly cool stuff. One example: Advanced query optimization with partial or reverse indexes.
