<application>pg_dumpall</application> is a utility for writing out
(<quote>dumping</quote>) all Postgres databases of a cluster into
one script file. The script file contains SQL commands that can be
used as input to <xref linkend="app-psql" endterm="app-psql-title">

linkend="app-pgdump" endterm="app-pgdump-title"> for each database

global objects that are common to all databases.

Description
</title>
<para>
<application>pg_dumpall</application>
is a utility for dumping out all Postgres databases into one file.
It also dumps the pg_shadow table, which is global to all databases.
<application>pg_dumpall</application> includes in this file the proper commands
to automatically create each dumped database before loading.
</para>
<refsect1 id="app-pg-dumpall-usage">
<title>Usage</title>
<para>
<application>pg_dumpall</application> takes all <application>pg_dump</application>
options, but <option>-f</option>, <option>-t</option> and
<replaceable class="parameter">dbname</replaceable>
should be omitted.
To dump all databases:
<screen>
<prompt>$</prompt> <userinput>pg_dumpall &gt; db.out</userinput>
</screen>
</para>
<para>
Refer to
<xref endterm="app-pgdump-title" linkend="app-pgdump-title">
for more information on this capability.
To reload this database use, for example:
<screen>
<prompt>$</prompt> <userinput>psql -f db.out template1</userinput>
</screen>
(It is not important to which database you connect here since the
script file created by <application>pg_dumpall</application> will
contain the appropriate commands to create and connect to the saved
databases.
