I don't believe in 'spoon feeding' people the answers to complex issues, like clearing things out of a live PostgreSQL database. I expect people to have a grasp of the basics before I plunge in and help them. If he went out and bought a PostgreSQL book, or even a copy of 'SQL for Dummies', and started learning the basics, then he will acquire skills that will help him way beyond Final Cut Server.
I wasn't really 100% certain of the answer to the '..what page?' question, since I have not obtained or looked through the new book.
