I should add that because I could not find
Postgresql in
the Muon collection, i installed Postgresql from the Command Line.
Subsequently there after not finding a few more packages in Muon,
the Synaptic Package Manager was installed, it told me that Postgr...
was installed and that the version was supported.

I guess that I was then expecting to find it through the Kickoff
Application Launcher. A bit more to learn about 12.04 I suppose.
