commit    84f1bf4afa5e7c329ca4dd908334205f8282c398
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date:     Wed Nov 12 19:19:03 2025 +0000
First released in: 14.21, 15.16, 16.12, 17.8, 18.2

    Clear 'xid' in dummy async notify entries written to fill up pages
    
    Before we started to freeze async notify entries (commit 8eeb4a0f7c),
    no one looked at the 'xid' on an entry with invalid 'dboid'. But now
    we might actually need to freeze it later. Initialize them with
    InvalidTransactionId to begin with, to avoid that work later.
    
    Álvaro pointed this out in review of commit 8eeb4a0f7c, but I forgot
    to include this change there.
