postgresql - initialize

I was interested in setting up postgreql as the Amarok backend, since reading that the default sqllite and mysql databases were much slower than postgresql once a collection became large. I read a primer at this Ubuntu forum, but it appeared that some of the commands there were outdated, or only applied in the Ubuntu environment.

The situation seemed worthy of a research effort; postgresql obviously has a myriad of uses beyond Amarok, and the Amarok example was apparently not the basic "single user" implementation.
