Sometimes technology isn't enough

I'm an enterprise java developer.  I love writing scalable servers in JEE land, which usually involve a database back-end.  The current server that I'm architecting has been using the Mysql 5.0 database and we have been amazed with the performance.  Database purists have been bugging me to switch to Postgres because of its rich feature set.  I haven't messed with Postgres since college but I have over 8 years experience with MySQL.  Still, I evaluated Postgres and found it to be a very nice database.  

So if Postgres is a more mature database with a richer feature set why do so many people still use MySQL?  Easy... community and marketing!  While at Borders book store I found 2 full shelves on MySQL, and only ONE book on Postgres.  If you have the money you can get on the phone to MySQL AS support or even have them come out to your business to train/troubleshoot.  I love open source software and both databases can be considered that, but MySQL has done a very good job at creating a service-oriented company behind their offering while Postgres has tried to stay with the purists. 

So my final decision was to stay with MySQL, not because it was the better database, but because if something went wrong I'd have more options on how to get things solved.
