I worked at one data-heavy startup where things were on MySQL and even with a lot of consulting by Percona, eventually it just couldn't keep up with our needs, and the project was ported to PostgreSQL. I've worked on other projects that were less data intensive and MySQL worked fine though.
If given a choice, I'll take PostgreSQL any day, but I do understand that people are hesitant to change database whey they don't need to. If you are encountering trouble though, by all means, move on.
