Debian has a mechanism exactly like this.

However it is my understanding (possibly incorrect) that the right way
to deal with this with RPM is using virtual provides, ie each database
would have this:

  Provides: database

Which allows any package that needs "a database" to require that.

I'm not exactly sure how requiring mysql or postgresql would work out
in reality, since they have quite different capabilities and SQL
syntax.

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
