Postgresql seems more popular from reading blogs, news sites, etc because it is moving up in popularity while mysql is moving down. So there is more talk about it, even though there is still less usage. All the people switching to postgresql from mysql and talking about how much better it is, all the people hearing that and asking about it, etc. Mysql is still more popular, notice how lots of the typical PHP turdware doesn't even support postgresql for example.
