Oracle's wonderfully featureful, but if you're not already an Oracle shop, you'd be foolish to bring it in. It's difficult to learn and administer, which is why "Oracle DBA" is such a great job title to hold (job security!)
SQL Server is more lightweight, but it naturally ties you into the Windows platform, if you want to deploy on some other operating system... tough. Many administrators love it, some hate it. The spatial support is also pretty new, which means support for it is still building. However, it is Microsoft, so it'll only get stronger over time. PostGIS is easy to install and easy to use, it has a clear simple syntax, it's been around a long time, is stable and very fast.

Some basic topology support, but nothing to write home about, and more importantly there are no client tools that support it. Topology is a sexy slow dance between the underlying data model and the user-facing application that exposes the model, and the difficult part is on the user-facing side. This is why ESRI's topology stuff remains more-or-less the only stuff in use -- because they nailed the user-facing side. > b. Versioning, which is not available in Postgres You can build versioned tables easily enough with some simple rules and triggers. Again, the question is what user-facing application you are planning to use and what your use case is going to be. > On a related note, can we edit directly on PostGIS using MapInfo, Yes > ArcGIS Desktop, Yes, with zigGIS.

Yes, they do. As does gvSIG, and I think MapWindow. Also web-based tricks, like WFS editing through openlayers and geoserver. Or through openlayers and featureserver. Or through geoext and mapfish.
