I just completed a presentation for my local PostgreSQL User Group (the Portland PUG) and gave it last Thursday. I need to add some updates to clarify things and round out some of it, but here it is as I gave it.
Hopefully there are others who will find it useful.
As a side note, there are NOTES on some of the slides to go along with the material being presented.
I need to fix these URLs...They are not correct going forward.
