MySQL might have a problem with Niagara, but it doesn't seem like it has the severe concurrency vulnerability you speak of.
There are many reasons to pick PostgreSQL, but this one doesn't seem to be a general thing. In general, MySQL seems to have problems with some kinds of threading, since their perfomance on Mac OS X is crappy as well for that reason.
