 Intro

 **pg_view** is a powerful command-line tool that offers a detailed, real-time view of your PostgreSQL database and system metrics. It combines the indicators commonly displayed by sar or iostat with output from PostgreSQL's process activity view, and presents global and per-process statistics in an easy-to-interpret way.

 By default, pg_view assumes that it can connect to a local PostgreSQL instance with the user postgres and no password. Some systems might require you to change your pg_hba.conf file or set the password in .pgpass. You can override the default user name with the -U command-line option or by setting the user key in the configuration file (see below).

 How pg_view works
-==============
+=================
 
 pg_view queries system/process information files once per second. It also queries the filesystem to obtain postgres data directory and xlog usage statistics. Please note that the latter function might add an extra load to your disk subsystem.

 If the auto-detection code works for you, you can select a single database by specifying the database instance name (in most cases, it will match the last component of $PGDATA) with the ``-i`` command-line option. If there is more than a single instance with the same name, you can additionally specify the required PG version with ``-V``.
