I don't understand your classification of PostgreSQL as "the bazaar", and MySQL as "the cathedral"; if anything, MySQL exemplified the bazaar model of incorporating almost any half-baked idea in the rush to regularly ship features, while PostgreSQL has always taken the approach of shipping when it's done. PostgreSQL's careful approach has always required "cathedral" centralization of technical management to ensure that things are done correctly, or not at all. I also have to question the assertion that Linux provides an objective example of well-written software, when the code quality and issues present in Linux are most reminiscent of MySQL. Relative to a so-called "cathedral" model such as FreeBSD's (or PostgreSQL's), Linux's software development model produces: 1) Code of considerably lower overall quality than that of FreeBSD in terms of bug count, maintainability, and simple consistency. 2) Poor (and often immediately replaced) architectural design designs that must be supported indefinitely. 3) Additional cost levied against downstream consumers of the product; simply shipping a reliable kernel requires considerable effort on the part of downstream distributions.
