The <xref linkend="pgarchivecleanup"> module
is often used in <varname>archive_cleanup_command</> for
single-standby configurations, for example:
-<programlisting> archive_cleanup_command = 'pg_archivecleanup /mnt/server/archivedir %r' </programlisting>
+<programlisting>archive_cleanup_command = 'pg_archivecleanup /mnt/server/archivedir %r'</programlisting>
Note however that if multiple standby servers are restoring from the
same archive directory, you will need to ensure that you do not delete
WAL files until they are no longer needed by any of the servers.
To create a base backup of the server at <literal>mydbserver</literal>
and store it in the local directory
<filename>/usr/local/pgsql/data</filename>:
- <screen>
- <prompt>$</prompt> <userinput>pg_basebackup -h mydbserver -D /usr/local/pgsql/data</userinput>
- </screen>
+<screen>
+<prompt>$</prompt> <userinput>pg_basebackup -h mydbserver -D /usr/local/pgsql/data</userinput>
+</screen>
</para>
<para>
To create a backup of the local server with one maximum compressed
tar file for each tablespace, and store it in the directory
<filename>backup</filename>, showing a progress report while running:
- <screen>
- <prompt>$</prompt> <userinput>pg_basebackup -D backup -Ft -Z9 -P</userinput>
- </screen>
+<screen>

To create a backup of a single-tablespace local database and compress
this with <productname>bzip2</productname>:
- <screen>
- <prompt>$</prompt> <userinput>pg_basebackup -D - -Ft | bzip2 > backup.tar.bz2</userinput>
- </screen>
+<screen>

(this command will fail if there are multiple tablespaces in the
database)

For example, <parameter>source_sql</parameter> might produce a set
something like:
<programlisting>
- SELECT row_name, extra_col, cat, value FROM foo ORDER BY 1;
-
- row_name extra_col cat value
- ----------+------------+-----+---------
- row1 extra1 cat1 val1
- row1 extra1 cat2 val2
- row1 extra1 cat4 val4
- row2 extra2 cat1 val5
- row2 extra2 cat2 val6
- row2 extra2 cat3 val7
- row2 extra2 cat4 val8
+SELECT row_name, extra_col, cat, value FROM foo ORDER BY 1;
