Clear 'xid' in dummy async notify entries written to fill up pages
Before we started to freeze async notify entries (commit8eeb4a0),no one looked at the 'xid' on an entry with invalid 'dboid'. But nowwe might actually need to freeze it later. Initialize them withInvalidTransactionId to begin with, to avoid that work later.Álvaro pointed this out in review of commit8eeb4a0, but I forgotto include this change there.Author: Álvaro Herrera <alvherre@kurilemu.de>Discussion:https://www.postgresql.org/message-id/202511071410.52ll56eyixx7@alvherre.pgsqlBackpatch-through: 14
