v11-0001 has a couple issues:
The first is that i_relallfrozen is undefined in versions earlier than
18. That's trivial to fix, we just add "0 AS relallfrozen," in the
earlier versions, but still refrain from outputting it.
The second is that the pg_upgrade test (when run with
olddump/oldinstall) compares the before and after dumps, and if the
"before" version is 17, then it will not have the relallfrozen argument
to pg_restore_relation_stats. We might need a filtering step in
adjust_new_dumpfile?
Attached new v11j-0001

Jeff Davis
