Conventions

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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The final query is a bit more complicated since it uses a CASE statement."

A block of code is set as follows:

SELECT name, setting
 
 FROM pg_settings
 
WHERE context = 'postmaster';

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

sudo apt-get install postgresql-9.3-pgfincore
