In section 3.3, the example for SQL Playground does not work with
Postgresql (I had that database installed, not sqlite). What happens
with a PostgreSQL specification in dev.cfg is that the table creation
fails because "user" is a keyword. Changing the class from class User
to anything else solves the problem.
On p. 34, there is a referral to a 'goodbye method' in the example in
Chapter 2. As far as I can tell, there is no mention of the goodbye
method in Ch. 2.
