<para>
Specify the compression method and/or the compression level to use.
The compression method can be set to <literal>gzip</literal>,
<literal>lz4</literal>, <literal>zstd</literal>,
or <literal>none</literal> for no compression.
A compression detail string can optionally be specified. If the
detail string is an integer, it specifies the compression level.
Otherwise, it should be a comma-separated list of items, each of the
form <literal>keyword</literal> or <literal>keyword=value</literal>.
Currently, the supported keywords are <literal>level</literal> and
<literal>long</literal>.
</para>
<para>
If no compression level is specified, the default compression
level will be used. If only a level is specified without mentioning
an algorithm, <literal>gzip</literal> compression will be used if
the level is greater than <literal>0</literal>, and no compression
will be used if the level is <literal>0</literal>.
</para>
<para>
For the custom and directory archive formats, this specifies compression of
individual table-data segments, and the default is to compress using
<literal>gzip</literal> at a moderate level. For plain text output,
setting a nonzero compression level causes the entire output file to be compressed,
as though it had been fed through <application>gzip</application>,
<application>lz4</application>, or <application>zstd</application>;
but the default is not to compress.
With zstd compression, <literal>long</literal> mode may improve the
compression ratio, at the cost of increased memory use.
</para>
<para>
The tar archive format currently does not support compression at all.
