Some things in that book will still be accurate and informative. The
problem is that you, as a beginner, won't know which things are still
good and which are obsolete.

I'd suggest:

- Developer documentation in our primary docs
- Developer FAQ on the wiki
- Bruce's presentations on various internals
- Tom's presentations on how the query planner works
- Various other people's presentations on other aspects, such as foreign
data wrappers, event triggers, etc.

Unfortunately, there's no central index of presentations.

I'm a big fan of "learn by doing", and here's a program which would
bring you up on a LOT of PostgreSQL:

1. Write a few of your own C functions, including trigger functions and
an operator.

2. Write your own foreign data wrapper for something.

3. Write your own Type, including input/output functions, stats
estimation and custom indexing.
