You're really expecting us to intuit a lot from this amount of detail, aren't you? But okay, I'll guess: I think this is a view on pg_stat_activity, and it's not accounting for the fact that pg_stat_activity gained some columns between v12 and v14. Probably your best bet is to drop that view, do the upgrade, and recreate the view with adjustments. regards, tom lane
