You didn't show us the command that was causing the error.  I am
thinking it might be a system view or function that references a renamed
system column.  I suggest dropping the view/function in the old cluster,
running pg_upgrade, then recreating the view with the new column name. 
Also, check the release notes for renamed columns.

Well, we can see that the problematic view is named "pg_stat_activity",
but why would pg_dump have dumped a system view?  I am thinking that the
source database contains a duplicate (and now obsolete) copy of the
pg_stat_activity view.  Probably just getting rid of that would do the
trick.

Thanks Tom
I have dropped the view and upgrade successful
Thanks for your quick response
