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.
