FWIW, I've found the Postgres documentation to be a little less easy for a novice to wrap their head around, but substantially higher quality than the MySQL documentation. Just remember that the Postgres documentation has sections that are purely reference material and sections that are mostly tutorials.
When in doubt, play around and make notes on what you did so when you accidentally burn it all down you can remember to not do the same thing twice. ;)
