<title>Backup and Restore</title>
As any other <productname>Postgres</> client application,
<application>pg_dump</> will by default connect with the database
user name that is equal to the current Unix user name. To override
- this, either specify the <option>-u</option> option to force a prompt for
- the user name, or set the environment variable
- <envar>PGUSER</envar>. Remember that <application>pg_dump</>
- connections are subject to the normal client authentication
- mechanisms (which are described in <xref
+ this, either specify the <option>-U</option> option or set the
+ environment variable <envar>PGUSER</envar>. Remember that
+ <application>pg_dump</> connections are subject to the normal
+ client authentication mechanisms (which are described in <xref
linkend="client-authentication">).
</para>
you have database superuser access, as that is required to restore
the user and group information.
</para>
-
- <para>
- <application>pg_dumpall</application> has one little flaw: It is
- not prepared for interactively authenticating to each database it
- dumps. If you are using password authentication then you need to
- set it the environment variable <envar>PGPASSWORD</envar> to
- communicate the password the the underlying calls to
- <application>pg_dump</>. More severely, if you have different
- passwords set up for each database, then
- <application>pg_dumpall</> will fail. You can either choose a
- different authentication mechanism for the purposes of backup or
- adjust the <filename>pg_dumpall</filename> shell script to your
- needs.
