     <varlistentry>
+      <term><option>--if-exists</option></term>
+      <listitem>
+       <para>
+        Do not error out when <option>--drop-slot</option> or
<option>--start<option> are
+        specified and a slot with the specified name does not exist.
+       </para>
+      </listitem>
+     </varlistentry>

I understand the --drop-slot part.  But I don't understand what it means
to ignore a missing replication slot when running --start.

The same option should be added to pg_receivewal as well.
