Apart from the database, I believe the target file also needs to be
specified. Should we include this option also along with dbname:
+ <group choice="plain">
+ <group choice="req">
+ <arg choice="plain"><option>-d</option></arg>
+ <arg choice="plain"><option>--dbname</option></arg>
+ </group>
+ <replaceable>dbname</replaceable>
+ </group>

pg_recvlogical -U postgres --start -S test -d postgres
pg_recvlogical: error: no target file specified
