<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.
