What do you mean by MySQL avoiding an additional database dependency?

[charliedevolve]

I think he meant that MySQL is the only supported DB for Wordpress, and while you might be able to get it running on another DB after jumping through some hoops, it's probably not worth the effort.

IIRC PHP has built-in support for MySQL out of the box.

Well, technically it's a "PHP extension", just one that several distributions include by default.
