I've had requests from a couple of businesses to see results of
infomal MySQL
+InnoDB vs. PostgreSQL tests.    I know that we don't have the setup
to do full formal benchmarking, but surely someone in our community
has gone head-to-head on your own application?     

how does someone compare an Apache+PHP+MySQL "thing" against something
implemented with half the stuff done in stored procedures and the
entire business model guarded by referential integrity, custom
triggers and whatnot?

Seriously, I am tired of this kind of question. You gotta get bold
enough to stand up in a "meeting" like that, say "guy's, you can ask
me how this compares to Oracle ... but if you're seriously asking me
how this compares to MySQL, call me again when you've done your
homework".   

Actually, before saying anything in public about their products, check
out what they require for use of their protected trademarks.
<http://www.mysql.com/company/trademark.html>

To wit, they indicate that:
 "The MySQL AB Marks may not be used in a manner or with respect to products that will decrease the value of the MySQL AB Marks or otherwise impair or damage MySQL AB's brand integrity, reputation or goodwill"

It seems to me that presenting a benchmark that did not favor their
product could be quite reasonably considered to be an "impairment" of
their integrity, reputation, or goodwill, and therefore be something
worthy of legal attack. 

It depends on how it is presented. Basically you just don't offer an opinion on the matter.
For example...

MySQL was 10x slower than PostgreSQL in this test....

Instead you could use something like.

We performed the following test.

MySQL scored this much
PostgreSQL scored this much

Notice no use of explaination.....
