There are currently a lot of discussions about the different types of DBAs. When it comes to patching, the DBA type is important.

Some DBAs are very conservative: do not use new features, do not upgrade to ‘.1′ releases, because every change can break anything. At least, maybe just patch to SPU for the security fixes.
