commit    59aeb693f67fc15dfa58e2fdada2a70ce1004660
Author:   Álvaro Herrera <alvherre@kurilemu.de>

First released in: 17.7, 18.1

    pg_createsubscriber: Fix error complaining about the wrong thing
    
    The code updates the system identifier, then runs pg_walreset; if the
    latter fails, it complains about the former, which makes no sense.
    Change the error message to complain about the right thing.
    
    Noticed while reviewing a patch touching nearby code.
