[Feature] Install/Maintenance Process [MySQL 5.1] Still Easiest. There are a lot of prepackaged products with it and its install rarely fails. [PostgreSQL 8.4] Medium (I put PostgreSQL at medium because on occasion we have run into issues where we have manually init the db on Windows. Those are rare though. On Linux its still the deal that MySQL often comes pre-installed for you and for PostgreSQL you have to figure it out yourself or they give you some super antiquated version. With PostgreSQL Yum respository its much easier now if you manage your own box. [Microsoft SQL Server 2008] 
Most time-consuming to install and most dependencies, but lots of wizards to help you forget everything and mail you when somethng bad happens (non-free versions)
