Those who already use Postgres are not going to switch to MySQL based on this. MySQL users who can see themselves hitting a substantial size (e.g. those who fear they may be herded in the direction of "upgrade to Oracle to get that particular feature you think MySQL lacks") will probably start giving Postgres a hard look. The website-in-a-box users are unlikely to even know that Oracle will own MySQL and are not going to change. The big question is how big is that middle category. I don't think it is particularly large now, but this is the time for the Postgres community to start getting aggressive in putting together new features, lowering the initial learning curve, and evangelizing their product.
