I ran "pg_dumpall --globals-only --no-role-passwords" on the source

the backup.
Some questions:
1) The backup was from a Postgres 12.x database using a version 12 or
higher instance of pg_backup?
pg_dump and pg_restore are 12.11 from RHEL8.
3) What if you run without --jobs?
It runs without error. Add "--jobs=2" and the errors appear.
Hmm, that is beyond me.
1) I did notice that the pg_restore errors all where; ERROR: permission
denied for schema strans
2) They all occurred during CREATE INDEX or COPY, which would be the part
where --jobs kicks in.
To me it looks like out of order execution where the jobs starting on
their tasks before the main task got done granting permissions. I just
have no idea how that could happen.
I was afraid you were going to say that.
The work-around is to:
pg_dump $SRCDB --schema-only | grep -e '^\(GRANT|REVOKE\)' > all_GRANT.sql
pg_dump $SRCDB --schema-only | grep OWNER > all_OWNER.sql
pg_restore --jobs=X --no-owner $NEWDB
psql $NEWDB -f all_OWNER.sql
psql $NEWDB -f all_GRANT.sql
This is, of course, why we need to test the backup/restore process.
