        This option should be specified if the replication client

        sent to the server.

        The compression method can be set to <literal>gzip</literal>,
        <literal>lz4</literal> (if <productname>PostgreSQL</productname>
        was compiled with <option>--with-lz4</option>) 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 <replaceable>keyword</replaceable> or
        <replaceable>keyword=value</replaceable>.
        Currently, the only supported keyword is <literal>level</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 0, and no compression will be used if the level
        is 0.

       <para>
        The suffix <filename>.gz</filename> will automatically be added to

    The following command-line options control the database connection parameters.

      <term><option>-d <replaceable class="parameter">connstr</replaceable></option></term>
      <term><option>--dbname=<replaceable class="parameter">connstr</replaceable></option></term>
      <listitem>
       <para>
        Specifies parameters used to connect to the server, as a <link
        linkend="libpq-connstring">connection string</link>;  these
        will override any conflicting command line options.
       </para>
       <para>
        This option is called <literal>--dbname</literal> for consistency with other
        client applications, but because <application>pg_receivewal</application>
        doesn't connect to any particular database in the cluster, any database
        name included in the connection string will be ignored by the server.
        However, a database name supplied that way overrides the default
        database name (<literal>replication</literal>) for purposes of
        looking up the replication connection's password
