Conventions

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

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "In this case, the \timing command will tell psql to show the runtime of a query."

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

test=# CREATE TABLE t_test (id serial, name text); 
CREATE TABLE 
test=# INSERT INTO t_test (name) SELECT 'hans'  
FROM generate_series(1, 2000000); 

New terms and important words are shown in bold.
