Finally I finished the first volume of the PostgreSQL book administration.
The book is free to download on slideshare or, if you want the hard copy there is the button to order on lulu.com.
I'll build an ebook version in the next days and I'll make it available on amazon's kindle and the kobo.
I hope this book will spread the knowledge on PostgreSQL.
Anyway, I've not finished. I've already started a second volume and a manual for the developers willing to learn the noble art of the SQL writing.
