Digg and Slashdot use MySQL databases, so clearly they *can* be made to
support a high-load, high-performance, limited-write style web
application.
You might remember a few months back when SlashDot had to turn off
threaded replies because the schema for the parent-child field was still
an UNSIGNED INT4 instead of an UNSIGNED INT8, and they reached the
maximum value of the field (16.7 million). Obviously, I have no
knowledge of the server configuration, hardware configuration, or
schema, but in-the-wild examples of high performance MySQL installations
are trivial to find (as are PostgreSQL installations such as the .org
DNS TLD root).
I'd like to see a tuned MySQL vs a similarly tuned PostgreSQL system
(that is, fsync in the same state and with the same level of ACID
compliance) subject to a battery of test schema types (OLTP, OLAP,
etc.).

That depends greatly on what you're doing with it. Generally, as soon
as you start throwing a multi-user workload at it, MySQL stops
scaling. http://tweakers.net recently did a study on that.
