In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "A table called t_user is used to store the users in our system."

A block of code is set as follows:

test=# CREATE TABLE t_test (t date);
CREATE TABLE
test=# INSERT INTO t_test VALUES (now()) 
RETURNING *;

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

pgbouncer=# SUSPEND;
SUSPEND

Any command-line input or output is written as follows:

psql -p 6432 -U zb pgbouncer
psql (9.2.4, server 1.5.4/bouncer)
WARNING: psql version 9.2, server version 1.5.
         Some psql features might not work.
Type "help" for help.
